A case of COVID-19-related acute genital ulceration in a male

COVID-19 is a viral infection which can present with various clinical manifestations. While it primarily affects the respiratory tract, several other manifestations including skin involvements have been reported. Dermatologic manifestations are uncommon, and its prevalence is not well-known. In COVID-19, there have been two reports of acute genital ulceration to date, and both are female. Here, we report a male patient with COVID-19 complicated by acute genital ulceration in the course of the illness

Omental infarction in mild Covid-19 infection

COVID-19 is an infection which can present with various clinical manifestations. While it affects respiratory tract primarily, several other manifestations including gastrointestinal involvements have been reported. The prevalence of all gastrointestinal complaints is approximately 17 percent and diarrhea, nausea/vomiting and abdominal pain are the most common symptoms. In COVID-19, acute abdominal pain requiring surgical evaluation and abdominal imaging is uncommon and there is also a lack of knowledge about COVID-19 related gastrointestinal complications. Here, we report a case of mild COVID-19 infection complicated by omental infarction during the course of the illness

Female Genital Tuberculosis: Five Case Reports

Female genital tuberculosis (FG-TB) is an important disease leading to substantial morbidity including infertility and abnormal vaginal bleeding. While the incidence of FG-TB is 1% in developing countries. Due to its subtle presentation, many cases are overlooked and diagnosed incidentally. Accordingly, the actual incidence of FG-TB is unknown. The definitive diagnosis of the disease is based on histopathological or microbiological examination but in most cases, the bacteriological test is overlooked. In addition, there is no specific laboratory or imaging evaluation to distinguish FG-TB from others. The first step in the diagnosis of FG-TB is suspicion of the disease. In the case of infertility, FG-TB should be included in the differential diagnosis in developing countries after excluding other common diseases and tissue biopsy should be sent for not only histopathology but also microbiological investigations

New and Accurate Synthesis Formulas for Asymmetric Coplanar Stripline with an Infinitely Wide Strip

New and accurate synthesis formulas for the asymmetric coplanar stripline with an infinitely wide strip (ACPS-IWS) are presented. They are obtained by using a differential evolution algorithm (DEA) and particle swarm optimization (PSO) algorithm, and are useful to microwave engineers for accurately computing the physical dimensions of ACPS-IWS. The average percentage errors of the synthesis formulas found by using DEA and PSO are calculated to be 0.85% and 1.62%, respectively, for 4913 ACPS-IWS samples having different electrical parameters and physical dimensions, as compared with the results of quasi-static analysis

Synthesis formulas for multilayer homogeneous coupling structure with ground shielding

This paper presents new and accurate synthesis formulas for the multilayer homogeneous coupling structure with ground shielding (MHCS-WGS). The synthesis formulas are obtained by means of a differential evolution algorithm (DEA), and are useful to microwave engineers for accurately calculating the physical dimensions of MHCS-WGS. The average percentage error is calculated to be 0.8% for 13614 MHCS-WGS samples having different electrical parameters and physical dimensions, as compared with the results of quasi-static analysis

Acromioclavicular Joint Septic Arthritis Without Any Underlying Disease: A Case Report

Septic arthritis is an emergency disease. Early diagnosis and appropriate antibiotic therapy are important for preventing morbidity. The acromioclavicular joint is very rarely involved in septic arthritis. We report a case with acromioclavicular joint septic arthritis due to Staphylococcus aureus without any risk factor and the treatment of our patient with antibiotics for eight weeks

Adaptive neuro-fuzzy models for conventional coplanar waveguides

© 2008, Electromagnetics Academy.In this work a new method based on the adaptive neuro-fuzzy inference system (ANFIS) was successfully introduced to determine the characteristic parameters, effective permittivities and characteristic impedances, of conventional coplanar waveguides. The ANFIS has the advantages of expert knowledge of fuzzy inference system and learning capability of neural networks. A hybrid-learning algorithm, which combines least-square method and backpropagation algorithm, is used to identify the parameters of ANFIS. There are very good agreement between the results of ANFIS models, experimental works, conformal mapping technique, spectral domain approach and a commercial electromagnetic simulator, MMICTL

Accurate synthesis formulas obtained by using a differential evolution algorithm for conductor-backed coplanar waveguides

In this paper, accurate synthesis formulas obtained by using a differential evolution (DE) algorithm for conductor-backed coplanar waveguides (CBCPWs) are presented. The synthesis formulas are useful to microwave engineers for accurately calculating the physical dimensions of CBCPWs. The results of the synthesis formulas are compared with the theoretical and experimental results available in the literature. A full-wave electromagnetic simulator IE3D and experimental results are obtained in this work. The average percentage error of the synthesis formulas obtained by using DE algorithm is computed as 0.67% for 1086 CBCPW samples having different electrical parameters and physical dimensions, as compared with the results of quasi-static analysis
