Validation Of A Real-Time Pcr Laboratory Developed Test For The Detection Of Pneumocystis Jirovecii In Bronchoalveolar Lavage Samples, Caitlyn Moon

Honors Scholar Theses

Pneumocystis jirovecii is an opportunistic, host-obligate fungal pathogen responsible for causing P. jirovecii pneumonia (PJP) in humans. PJP is treated with trimethoprim-sulfamethoxazole (TMP-SMX), a strong broad-spectrum antibiotic that carries risk of renal and hepatotoxicity. Therefore, rapid diagnosis or exclusion of PJP is crucial to ensure PJP-positive patients receive effective treatment and PJP-negative patients avoid unnecessary antibiotics. Unlike most microorganisms, P. jirovecii cannot be cultured, presenting complications for the typical methods of diagnosing fungal pathogens. Historically, the gold standard for diagnosis was direct microscopic examination with stains such as methenamine silver and calcofluor white, but this diagnostic technique requires highly skilled …

Audit Of The Impact Of The Pause In The National Screening Service For Breast Cancer During The Covid-19 Pandemic, Ava Coakley

International Undergraduate Journal of Health Sciences

In Ireland there is a free national screening service for breast cancer called BreastCheck. BreastCheck invites women aged fifty to sixty-nine to have screening mammograms once every two years to detect any densities in their breast mammogram which could indicate breast cancer. If densities are seen on a mammogram a breast core is sampled and sent to a histopathology laboratory where a part of the tissue is examined by a consultant pathologist using a microscope. Further tests can then be performed on this sample if it is diagnosed as breast cancer. Tests include immunohistochemistry and dual in-situ hybridisation (DISH). BreastCheck …

Molecular Detection Of Entamoeba Histolytica In Diarrheic Fecal Samples From Patients Attending National Hepatology And Tropical Medicine Research Institute, Azza Hasan Abbas, El Shahat Ahmed Elshahat, Heba Mohamed Abdelglil

Journal of Medicine in Scientific Research

Background: Amoebiasis is a worldwide disease caused by Entamoeba histolytica infection. The true prevalence is unknown due to the difficulty in distinguishing Entamoeba histolytica from non-pathogenic amoebas especially when microscopic diagnosis is performed, to overcome microscopy misidentification. Polymerase Chain Reaction (PCR) assay is necessary as a highly sensitive and specific technique. Objective: To determine the value of Real-Time PCR (RT.PCR) in the diagnosis of Entamoeba histolytica in the stool samples of diarrheic patients attending NHTMI versus microscopy, copro- antigen, and serum antibodies detection techniques. Subjects and Methods: A cross-sectional study was conducted on 150 diarrheic patients. Their stool samples were …
