1Pancreatic pseudocyst or a cystic tumor of the pancreas?显示文摘Pancreatic pseudocysts are the most common cystic lesions of the pancreas and may complicate acute pancreatitis, chronic pancreatitis, or pancreatic trauma. While the majority of acute pseudocysts resolve spontaneously, few may require drainage. On the other hand, pancreatic cystic tumors, which usually require extirpation, may disguise as pseudocysts. Hence, the distinction between the two entities is crucial for a successful outcome. We conducted this study to highlight the fundamental differences between pancreatic pseudocysts and cystic tumors so that relevant management plans can be devised. We reviewed the data of patients with pancreatic cystic lesions that underwent intervention between June 2007 and December 2010 in our hospital. We identified 9 patients(5 males and 4 females) with a median age of 40 years(range, 30–70 years). Five patients had pseudocysts, 2 had cystic tumors, and 2 had diseases of undetermined pathology. Pancreatic pseudocysts were treated by pseudocystogastrostomy in 2 cases and percutaneous drainage in 3 cases. One case recurred after percutaneous drainage and required pseudocystogastrostomy. The true pancreatic cysts were serous cystadenoma, which was treated by distal pancreatectomy, and mucinous cystadenocarcinoma, which was initially treated by drainage, like a pseudocyst, and then by distal pancreatectomy when its true nature was revealed. We conclude that every effort should be exerted to distinguish between pancreatic pseudocysts and cystic tumors of the pancreas to avoid the serious misjudgement of draining rather than extirpating a pancreatic cystic tumor. Additionally, percutaneous drainage of a pancreatic pseudocyst is a useful adjunct that may substitute for surgical drainage.Mohammad Ezzedien Rabie Ismail El Hakeem Mohammad Saad Al Skaini Ahmad El Hadad Salim Jamil Mian Tahir Shah Mahmoud Obaid 2014Chinese Journal of Cancer2014,33,2:2

6Real and Altered Fingerprint Classification Based on Various Features and Classifiers显示文摘Biometric recognition refers to the identification of individuals through their unique behavioral features(e.g.,fingerprint,face,and iris).We need distinguishing characteristics to identify people,such as fingerprints,which are world-renowned as the most reliablemethod to identify people.The recognition of fingerprints has become a standard procedure in forensics,and different techniques are available for this purpose.Most current techniques lack interest in image enhancement and rely on high-dimensional features to generate classification models.Therefore,we proposed an effective fingerprint classification method for classifying the fingerprint image as authentic or altered since criminals and hackers routinely change their fingerprints to generate fake ones.In order to improve fingerprint classification accuracy,our proposed method used the most effective texture features and classifiers.Discriminant Analysis(DCA)and Gaussian Discriminant Analysis(GDA)are employed as classifiers,along with Histogram of Oriented Gradient(HOG)and Segmentation-based Feature Texture Analysis(SFTA)feature vectors as inputs.The performance of the classifiers is determined by assessing a range of feature sets,and the most accurate results are obtained.The proposed method is tested using a Sokoto Coventry Fingerprint Dataset(SOCOFing).The SOCOFing project includes 6,000 fingerprint images collected from 600 African people whose fingerprints were taken ten times.Three distinct degrees of obliteration,central rotation,and z-cut have been performed to obtain synthetically altered replicas of the genuine fingerprints.The proposal achieved massive success with a classification accuracy reaching 99%.The experimental results indicate that the proposed method for fingerprint classification is feasible and effective.The experiments also showed that the proposed SFTA-based GDA method outperformed state-of-art approaches in feature dimension and classification accuracy.Saif Saad Hameed Ismail Taha Ahmed Omar Munthir Al Okashi 2023Computers, Materials & Continua2023,,1:0

8Telehealth utilization among Egyptian population and health institutional readiness:An exploratory study显示文摘Objective:This study aimed to assess the public’s perspectives and the health institutions’readiness for telehealth utilization in Egypt.Methods:A cross-sectional study design was employed,and data were collected from a convenient sample of 800 Egyptian citizens and 26 nursing administrators and information technology personnel from 16 governmental hospitals and 10 private hospitals between January and March 2022.The Egyptian community utilization of telehealth questionnaire and the telemedicine hospital readiness assessment were used to collect the data.Results:The results revealed that 35.1%of the general Egyptian population used telehealth services and 43%expressed willingness to use them in future.As perceived by the general Egyptian population,the most prevalent barriers to telehealth utilization were communication barriers(97.6%),lack of confidence in health professionals(77.6%),technological limitations(72.5%),the need for physical examination(25%),and privacy concerns(10%).Regarding hospital readiness,42%of governmental hospitals were not taking any initiative to implement telehealth services,and 15.4%were at the beginner level,meaning that some steps had been taken.However,the hospital was still far from being able to implement telehealth services.In contrast,private hospitals were either at the beginner or advanced level.Conclusion:Although the use of telehealth services in Egypt has increased,there is a need to address the barriers to public utilization and improve hospitals’readiness to implement telehealth services to enhance public usage.Basma Mohamed OSMAN Maaly Zayed MOHAMED Shaimaa Ali Mohamed ISMAIL Lamiaa Saad Abd ALLAH Marwa Mamdouh SHABAN 2023Journal of Integrative Nursing2023,5,3:0
9Effect of Co on Solidification Characteristics and Microstructural Transformation of Non-equilibrium Solidified Cu-Ni Alloys显示文摘Non-equilibrium solidification structures of Cu55Ni45 and Cu55Ni43Co2 alloys were prepared by the molten glass purification cycle superheating method.The variation of the recalescence phenomenon with the degree of undercooling in the rapid solidification process was investigated using an infrared thermometer.The addition of the Co element affected the evolution of the recalescence phenomenon in Cu-Ni alloys.The images of the solid-liquid interface migration during the rapid solidification of supercooled melts were captured by using a high-speed camera.The solidification rate of Cu-Ni alloys,with the addition of Co elements,was explored.Finally,the grain refinement structure with low supercooling was characterised using electron backscatter diffraction(EBSD).The effect of Co on the microstructural evolution during nonequilibrium solidification of Cu-Ni alloys under conditions of small supercooling is investigated by comparing the microstructures of Cu55Ni45 and Cu55Ni43Co2 alloys.The experimental results show that the addition of a small amount of Co weakens the recalescence behaviour of the Cu55Ni45 alloy and significantly reduces the thermal strain in the rapid solidification phase.In the rapid solidification phase,the thermal strain is greatly reduced,and there is a significant increase in the characteristic undercooling degree.Furthermore,the addition of Co and the reduction of Cu not only result in a lower solidification rate of the alloy,but also contribute to the homogenisation of the grain size.安红恩 Bih-Lii Chua Ismail Saad Willey Yun Hsien Liew 2024Journal of Wuhan University of Technology(Materials Science)2024,39,2:0
10Otoacoustic emissions value in patients with idiopathic sudden sensorineural hearing loss显示文摘Objectives:This study aimed to determine the prognostic value of otoacoustic emissions(OAEs)in idiopathic sudden sensorineural hearing loss patients.Methods:The study included 30 subjects with unilateral idiopathic sudden sensorineural hearing loss(ISSNHL).Each patient was evaluated four times:at baseline and after one week,one month,and three months of treatment.During each visit,each patient was subjected to full audiological history,otoscopic examination,basic audiological evaluations,and transiently evoked and distortion product otoacoustic emission(TEOAEs&DEOAEs).Results:The hearing thresholds(frequency range 250e8000 Hz)and word recognition scores of patients with detectable TEOAEs and DPOAEs improved significantly,whereas no significant improvements were observed in those with no response.Conclusion:Hearing improvement is better in patients with detectable TEOAEs and DPOAEs.As a result,TEOAEs and DPOAEs are recommended as routine tests in all SSNHL patients to predict outcomes and monitor treatment as TEOAEs and DPOAEs reflect the cochlear OHCs activity.Aya El-sayed El-sayed Gaafar Elshahat Ibrahem Ismail Hesham Saad Zaghloul 2022Journal of Otology2022,17,4:0
11Coverless Image Steganography System Based on Maze Game Generation显示文摘The trend of digital information transformation has become a topic of interest.Many data are threatening;thus,protecting such data from attackers is considered an essential process.Recently,a new methodology for data concealing has been suggested by researchers called coverless steganography.Coverless steganography can be accomplished either by building an image database to match its image subblocks with the secret message to obtain the stego image or by generating an image.This paper proposes a coverless image steganography system based on pure image generation using secret message bits with a capacity higher than the other traditional systems.The system uses the secret message to generate the stego image in the form of one of the Intelligence Quotient(IQ)games,the maze.Firstly,a full grid is generated with several specific rows and columns determined from the number of bits of the secret message.Then,these bits are fed to the full grid to form the maze game stego image.Finally,the generated maze game stego image is sent to the recipient.The experimental results,using the Bit Error Rate(BER),were conducted,and confirmed the strength of this system represented by a high capacity,perfect performance,robustness,and stronger hiding system compared with existing coverless steganography systems.Al Hussien Seddik Saad Mohammed S.Reda GamalM.Behery Ahmed A.El-harby Mohammed Baz Mohamed Abouhawwash Ahmed Ismail Ebada 2023Intelligent Automation & Soft Computing2023,38,11:0
