Background In general, histomorphologic examination of a prostate tissue is necessary after the prostatectomy. Aims This study was carried out to investigate a possibility of the usage of polarized light for the formation and analyse of infrared images of prostate cancer. Methods Experiments were carried out in isolated prostates. For the obtaining of prostate infrared images a light source in the spectral range of 840-900nm was used. Infrared light polarization measurement was performed using polarizers working in 700-2000nm. Infrared polarized light incident on a CCD camera matrix was converted into electrical signals and sent to the PC for the creating visible image.
Renal abscesses are uncommon in adults and are typically caused by gram-negative bacteria such as Escherichia coli, Proteus mirabilis, or Staphylococcus aureus. Nontyphoid Salmonella abscesses are infrequent. We discuss the case of a 27-year-old previously healthy female who developed a renal abscess due to Salmonella enterica. Abdominal computed tomography (CT) revealed a left renal abscess (size 11.6 cm × 8.2 cm) and 1.9 cm cyst in the right kidney. The urine and abscess aspirate cultures indicated the presence of gram-negative bacilli and lactose-negative Salmonella. A presumptive diagnosis of the left renal abscess was made. A urologist was consulted, and the patient was prepared for a left-sided nephrectomy. The patient's condition improved following treatment with a combination of piperacillin/tazobactam and moxifloxacin. Based on our experience, prompt recognition of nontyphoidal Salmonella as a potential cause of a renal abscess is important to prevent complications such as the extension of the abscess and the spread of the pathogen to adjacent structures.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
