The Buried Bumper Syndrome: External Bumper Extraction after Radial Mini Incisions and Replacement through an Adjacent Tract

Although considered as a safe method to provide long-term nutritional support, percutaneous endoscopic gastrostomy (PEG) may be complicated by a buried bumper syndrome (BBS), a life-threatening condition. Removal of the PEG tube with its buried bumper and reinsertion of a new PEG tube is often necessary. Since its description in 1988, less than 50 cases of BBS managed by external extraction of the buried bumper have been reported. We report a case of buried bumper that was removed by external traction without the need for endoscopic or laparoscopic treatment but with the need of two radial millimeter skin incisions after abdominal CT study and finally immediate PEG replacement but through an adjacent site

Results of prostatic biopsies in Algerian patients with an elevated PSA and/or suspicious digital rectal examination

Objective: to report on prostatic biopsy results in Algerian patients presenting with a suspicious Digital Rectal Examination (DRE) and\or an elevated total PSA.Methods: data collected on prepared index cards were age, result of DRE, rate of PSA and number of cores, as well as the histological result. The biopsies were performed by two urologist surgeons from Oran city, Algeria.Results: 331 patients had prostatic transrectal ultrasound-guided biopsies, the average (SD) age was 70.4 (8.7) years with a range 33 - 94 years. The most important age bracket was the one with subjects over 60 years. The DRE was suspicious in 41.69% of patients (138 of 331), and 44.20% of the suspect prostates on DRE were malignant. The average PSA was 42.2 ng/ml the rate of PSA >10 ng/ml constituted 72.57%. The number of biopsy cores was 12 for 129 biopsies, 49.2% of the biopsies revealed prostatic adenocarcinoma. The percentage of positive biopsies was 41.66% (21/48) when the PSA was between 4 and 10 ng/ml, and 33.33% (45/135) when the PSA exceeded 10 ng/ml. Among 47 scores of Gleason 59.7% patients had a score 7, 8.6% had a score < 7, and 31.8% had scores >7.Conclusion: 49.2% of 331 biopsies were positive for prostatic adenocarcinoma. Significant associations were found between age and cancer, between digital rectal examination and prostate biopsy results, and between PSA and number of positive cores

Static and vibration analysis of functionally graded beams using refined shear deformation theory

Static and vibration analysis of functionally graded beams using refined shear deformation theory is presented. The developed theory, which does not require shear correction factor, accounts for shear deformation effect and coupling coming from the material anisotropy. Governing equations of motion are derived from the Hamilton's principle. The resulting coupling is referred to as triply coupled axial-flexural response. A two-noded Hermite-cubic element with five degree-of-freedom per node is developed to solve the problem. Numerical results are obtained for functionally graded beams with simply-supported, cantilever-free and clamped-clamped boundary conditions to investigate effects of the power-law exponent and modulus ratio on the displacements, natural frequencies and corresponding mode shapes

Résultats de la biopsie prostatique chez les patients algériens avec un PSA élevé et/ou un toucher rectal suspect

Objectif: Rapporter les résultats de la biopsie prostatique à Oran chez des patients qui présentent un toucher rectal (TR) suspect et/ou une élévation du PSA total. Méthodes: Les données recueillies sur des fiches préétablies sont l’âge, le résultat du TR, le taux de PSA et le nombre de prélèvements, ainsi que le résultat anatomopathologique. Les biopsies ont été réalisées par deux chirurgiens urologues de la ville d'oran. Résultats: 331 patients ont eu des biopsies prostatiques transrectales écho guidées, l’âge moyen (SD) était de 70.4 (8.7) ans avec une limite inférieure de 33 ans et une limite supérieure de 94 ans. La tranche d’âge la plus importante est celle des sujets de plus de 60 ans. Le TR était suspect chez 41.69% (138 sur 331), et 44.20% des prostates suspectes au TR étaient histologiquement malignes, la moyenne du PSA chez les sujets qui ont eu des biopsies de prostate était de 42.2 ng/ml avec un écart type de 68.36 ng/ml, le taux de PSA >10 ng / ml a constitué 72,57%. Le nombre de carottes biopsiques était de 12 pour 129 biopsies. 49.2% des biopsies ont révélés un adénocarcinome de la prostate. Le pourcentage de biopsies positives est de 41.66% (21/48) lorsque le PSA était entre 4 et 10 ng/ml, ce taux est de 33.33% (45/135) lorsque le PSA dépasse 10 ng/ml. Sur les 47 scores de Gleason 59.7% avaient un score 7, 8.6% avaient un score  7. Conclusion: 49.2% des 331 biopsies colligées étaient positives pour adénocarcinome de la prostate. Des associations significatives ont été retrouvées entre l’âge et le cancer, les résultats du Toucher Rectal et la biopsie prostatique, ainsi qu'entre le taux de PSA et le nombre de carottes positives

Investigation of dynamic behavior of prestressed FRP plate intended for strengthening prestressed RC beam

International audienceStrengthening concrete beams by prestressed or not prestressed composite plates has become one of the widely used techniques in civil engineering with the aim of improving the durability of infrastructures, specifically against seismic solicitations. However, this type of reinforcement is quite new for prestressed concrete beams. Before using a composite plate for strengthening prestressed concrete beams, it is important to know its dynamic characteristics. In this paper, an analytical model based on the high-order theory and the laminate theory is proposed in order to well determine the free vibration characteristics of presetressed composite plate. The presence of prestressing tension effort in the composite plate, which was not taken into consideration in earlier studies for slender composite plates, is the main innovation of the current research. Parametric studies varying prestressing effort and fiber orientations are carried out in aim to find the best way to use the composite plate in the reinforcing of prestressed concrete beams. For comparative purposes, a finite element model is carried out in order to explore the behavior of the composite plate under several boundary conditions (B.Cs). As an important result, this research reveals that prestressing effort stiffens the composite plate and makes it a strong choice for reinforcing prestressed concrete beams by increasing natural frequencies and reducing deflexion. © 2023 Elsevier Lt
