Myometrial Abscess: A Complication of Myomectomy of a Large Lower-Uterine Segment Myoma

Background: This article describes a patient with a history of two early miscarriages. She presented with menorrhagia and a recurrence of multiple fibroids. Laparotomy and myomectomy were performed and were complicated by a myometrial abscess. The diagnosis and management of such a rare complication are described. Case: A 39-year-old African American female (gravida 3, para 1) presented with a history of two early miscarriages, menorrhagia, and a recurrence of multiple fibroids. An ultrasound (US) scan revealed an enlarged uterus with at least six uterine fibroids. Laparotomy and myomectomy were performed. Four weeks later, this patient presented with complaints of pelvic pain, nausea, vomiting, constipation, and a fever of 1 day's duration. A US scan revealed a slightly enlarged uterus caused by a possible infected hematoma. The patient was admitted to the hospital and she was started on intravenous antibiotics after a blood culture was obtained. A computed tomography (CT) scan of her abdomen and pelvis confirmed the diagnosis of a myometrial abscess. This patient underwent CT scan?guided placement of a ?pigtail? catheter in the myometrial abscess for continuous drainage. The result of the culture of the pus obtained from the abscess revealed the presence of multiple bacteria. The pigtail catheter was removed once there was no drainage 2 weeks after its initial insertion. Results: Two months after her discharge, a transvaginal US scan revealed that this patient's condition was essentially normal. Conclusions: This case report describes how a minimally invasive technique was used to manage a myometrial abscess, which is a complication of myomectomy. This report also illustrates the value of transvaginal US scanning for diagnosing such a pathology, and the roles US plays during management and follow-up.

Diverse exact solutions to Davey–Stewartson model using modified extended mapping method

In this study, we obtain solitary wave solutions and other exact wave solutions for Davey–Stewartson equation (DSE), which explains how waves move through water with a finite depth while being affected by gravity and surface tension. The study is conducted with the aid of the modified extended mapping method (MEMM). A variety of distinct traveling wave solutions are furnished. The obtained solutions comprise dark, bright, and singular solitary wave solutions. Additionally, Jacobi elliptic function solutions, exponential wave solutions, singular periodic wave solutions, rational wave solutions, and periodic wave solutions are also offered. To help readers physically grasp the acquired solutions, graphical representations of some of the extracted solutions are provided

Abstract: Building facades are one of the most important elements of the building envelope for their functions and impact on energy consumption. Windows are considered one of the most important elements of building facades that are given special importance by architects who resist any alternatives proposed by engineering teams, based on changing its location or proportions. This represents the problem of this study that aims to offer windows’ facades’ alternatives to enhance its thermal performance, with nearly no effect on its location or proportions, and employ Building Information Modeling and digital simulation applications in assessing the thermal performance of such alternatives to support the Architect in taking the suitable related design decisions. The study adopted a descriptive and experimental approach and concluded that the windows’ facades’ alternatives have a positive impact on enhancing facades’ thermal performance, and that the new technologies used by architects, whether at the level of applications or at the level of materials, have a major role in supporting the architect to assess any offered alternatives to enhance the thermal performance of building facades and avoid Potential problems that may arise in the early design stages

Supervised Learning Based Super-Resolution DoA Estimation Utilizing Antenna Array Extrapolation

In this paper, we introduce a novel algorithm that can dramatically reduce the number of antenna elements needed to accurately predict the direction of arrival (DOA) for multiple input multiple output (MIMO) radar. The new proposed algorithm predicts the received signal of a large antenna setup using reduced number of antenna by using coupled dictionary learning. Hence, this enables the MIMO radar to resolve more paths, which could not be resolved by the fewer antennas. Specifically, we overcome the problem of inaccurate DOA estimation due to a small virtual array setup. For example, we can use dictionary learning to predict 100 virtual array elements using only 25. To evaluate our algorithm, we used multiple signal classification (MUSIC) as a DOA estimation technique to estimate the DOA for non coherent multiple targets. The results show that using the predicted received signal, the proposed algorithm could resolve all the targets in the scene, which could not been resolved using only the received signal from the reduced antenna setup.Comment: 2020 IEEE 91st Vehicular Technology Conference (VTC2020-Spring

Detection and Identification of Helicobacter pullorum in Poultry Species in Upper Egypt

This work aimed to detect, identify and study the epidemiology of Helicobacter pullorum in avian species in Upper Egypt. A total of 1800 samples, including cloacal swabs, cecal swabs and livers were collected from chickens, turkeys and ducks in five different governorates in Upper Egypt. Using conventional phenotypic methods for isolation and identification, Helicobacter pullorum could be identified only from chickens with percentage 39.33% and no presence of the organism in turkeys and ducks. Sixteen randomly selected phenotypically identified Helicobacter pullorum isolates were confirmed using PCR assay based on 16S rRNA gene. In conclusion, conventional phenotypic methods for detection and differentiation of Helicobacter pullorum are often hampered by many limitations, while molecular methods, and PCR, in particular, have marked an important step forward in bacterial diagnostics and can provide a sensitive and rapid alternative method for detection and identification and highlights the potential of PCR technology in routine detection and identification of pathogens

Solitons in magneto-optic waveguides with Kudryashov’s law nonlinear refractive index for coupled system of generalized nonlinear Schrödinger’s equation using modified extended mapping method

In this work, we investigate the optical solitons and other waves through magneto-optic waveguides with Kudryashov’s law of nonlinear refractive index in the presence of chromatic dispersion and Hamiltonian-type perturbation factors using the modified extended mapping approach. Many classifications of solutions are established like bright solitons, dark solitons, singular solitons, singular periodic wave solutions, exponential wave solutions, rational wave, solutions, Weierstrass elliptic doubly periodic solutions, and Jacobi elliptic function solutions. Some of the extracted solutions are described graphically to provide their physical understanding of the acquired solutions

Differentiation of Infectious Bursal Disease Virus (IBDV) Strains in Experimentally Infected Chickens

Infectious bursal disease (IBD) is an acute, highly contagious, and immunosuppressive avian disease caused by IBD virus (IBDV). Differentiation of IBDV strains is crucial for effective vaccination programs and epidemiological investigations. In this study, a combination of clinical, histopathological examinations, immunohistochemistry and indirect immunofluorescence techniques were used to differentiate different IBDV strains. Sixty three weeks old chickens were divided randomly into five equal groups. Chickens of four groups were inoculated orally with different strains of IBDV. Chickens of the fifth group were kept as a control. Three chickens per group were euthanized at 3, 7, 14, 21 days post-inoculation (dpi). Euthanized chickens subjected to autopsy and tissue samples were collected in 10% neutral-buffered formalin for histopathology, immunohistochimestry and immunoflrourescence. The results revealed that clinical examination and histopathology cannot be used alone for differentiation of IBDV strains, while immunohistochemical and immunofluorescence techniques are reliable tools for differentiation of IBDV strains
