Scan to discover online Background & Objective: A simple approach to prevent close contact in healthcare settings during the COVID-19 outbreak is to train patients to collect their own nasopharyngeal and oropharyngeal swabs and deliver them to medical laboratories to have them processed. The aim of our study was to compare lab technician-with patientcollected oropharyngeal and nasopharyngeal samples for detection of the coronavirus disease 2019 (COVID 19) using rapid real-time polymerase chain reaction (rRT-PCR). Methods: Fifty adult patients with flu-like symptoms and radiologic findings compatible with atypical pneumonia who were admitted to the infectious diseases ward of Imam Khomeini Hospital Complex, Tehran, Iran, with a clinical diagnosis of COVID-19 from February 28 to April 27 of 2020 were randomly selected and entered in our study. Two sets of naso-and oropharyngeal swabs were collected, one set by a lab technician and the other by the patients, and the COVID-19 rRT-PCR test was performed. Results: Of 50 selected cases, in seven patients all collected naso-and oropharyngeal swabs tested positive, and in 22 patients all samples tested negative for COVID-19 in rRT-PCR. Discrepancies between rRT-PCR results of lab technician-and patientcollected swabs were observed in 12 nasopharyngeal and 13 oropharyngeal specimens. Positive lab technician-collected and negative patient-collected samples were observed in 10 and 5 nasopharyngeal and oropharyngeal specimens, respectively. Negative lab technician-collected and positive patient-collected samples were observed in two and seven nasopharyngeal and oropharyngeal specimens, respectively. The overall percentage of agreement among both nasopharyngeal and oropharyngeal swabs taken by a lab technician and patients was 76% with a kappa value of 0.49 (P=0.001). Conclusion: Based on our findings, lab technician-collected naso-and oropharyngeal swabs cannot be replaced by patient-collected ones with regard to COVID-19 rRT-PCR.
Co-infection of cystic echinococcosis and aspergillosis is a rare finding. The patient was a 10-year-old boy complaining of chest pain and malaise with a cyst in the right lung who underwent surgical resection of the cyst. Medical therapy with albendazole was started for the patient with the initial clinical impression of cystic echinococcosis. Later, the microscopic evaluation revealed a laminated layer of cystic echinococcosis involved by acute angle branching hyaline hyphae with septate. Thus, the diagnosis of a cystic echinococcosis and aspergillosis co-infection was established. Surgery is the mainstay of treatment along with anthelminthic and anti-fungal therapy, especially in immunocompromised patients.
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.
