To evaluate cone-beam computed-tomography (CBCT) images of the temporal bone for radiological delineation, metal artifacts, and accuracy for localization of six different electrode arrays after cochlear device implantation.

This retrospective study included 116 patients who underwent CBCT (120kV, 7.1mA) within 24 hours after cochlear device implantation. Exclusion criteria were anatomical abnormalities, and electrode misinsertion. Six different CI electrodes were implanted Advanced Bionics HiFocus Mid-Scala, Cochlear Contour Advance, Cochlear Slim-Straight, Cochlear Slim-Modiolar, MED-EL Flex 24 and MED-EL Flex 28. Two radiologists rated independently presence of metal artifacts, overall image quality, as well as dedicated visualization of the osseous spiral lamina, inner and outer cochlear wall, single electrode contacts, and electrode position using 5-point-Likert scales. IKK inhibitor Inter-rater agreement was calculated by using Cohen's kappa and intraclass correlation.

Of 116 patients, 94 (81.0%; 56.1 ± 16.9 yea greater spacing between contacts and contact size allow improved radiologic evaluation.

The COVID-19 pandemic indefinitely cancelled visiting medical student radiology electives across Canada. In response, the Canadian Association of Radiologists Resident & Fellow Section (CAR RFS) and Medical Student Network (MSN) developed and evaluated an online series for medical students to learn about Canadian radiology residency programs.

Medical students from any year of training were recruited through the MSN, local radiology interest groups, and social media to attend a 2-week online series of interactive sessions via Zoom with program representatives from Canadian radiology residency programs. A survey evaluating the online series, in particular its impact on residency and career planning, was administered to program representatives and students.

Fifteen of Canada's 16 radiology residency programs participated in the online series. A total of 212 students attended at least one session and nearly half were participating in the Canadian Resident Matching Service (CaRMS) this year. The postsurvey revealed that 77% of students agreed that the online series helped prepare them for CaRMS and ranking programs. The online series also benefited pre-CaRMS students as significantly more students were considering radiology as a specialty on the postsurvey compared to the presurvey. Students and program representatives agreed that this series should be held in future years, regardless of whether health and travel restrictions are lifted.

The CAR RFS and MSN hosted an online series for medical students to learn about radiology residency programs outside their home institution. Feedback was highly positive with important implications for the future CaRMS iterations for any specialty.

The pandemic of a novel coronavirus disease 2019 (COVID-19) caused by a severe acute respiratory coronavirus 2 (SARS-CoV-2) infection has been problematic worldwide. A new SARS-CoV-2 antigen test (LUMIPULSE

) was licensed and widely used in Japan since May 2020. We conducted this study intending to whether the automated quantitative CLEIA antigen test using a saliva sample is effective and valid for the diagnosis of COVID-19.

We analyzed and compared the diagnostic accuracy of both the automated quantitative CLEIA antigen test and real-time RT-PCR (rRT-PCR) using a saliva sample from individuals suspected as having COVID-19.

A total of 305 samples were collected and tested in Aichi Medical University Hospital and affiliated facilities from December 2020 until January 2021at our institute. Using reverse-transcription PCR as a reference, the AUROC of the automated quantitative CLEIA antigen test was 0.903 (95% confidential interval 0.845-0.962, p<0.001). The appropriate cut-off antigen level was 4.0pg/mL and had a sensitivity of 77.8%, a specificity of 99.6%, a positive predictive value of 98%, and a negative predictive value of 94.5%. On the other hand, the diagnostic accuracy of the antigen test decreased among patients among patients with COVID-19 with threshold cycle (Ct-value)≥27, which shows the AUROC was 0.795 (95%CI 0.687-0.907, p<0.001).

While the automated quantitative CLEIA antigen test from saliva specimen could be one of the most useful diagnostic tests for the diagnosis of COVID-19 in general practice, clinicians should know the limitations of the antigen test.

Pregnant women are also one of the risk populations for cryptococcosis. Reversal of Th2 to Th1 response following resolution of immunosuppression during the postpartum period can lead to overt clinical manifestations of a previously silent infection, resembling an immune reconstitution inflammatory syndrome. Here, we report a case of a 30-year-old woman who had an exacerbation of pulmonary cryptococcosis in the postpartum period mimicking an immune reconstitution inflammatory syndrome. In the present case, chest computed tomography showed multiple small nodules on the day of the delivery; however, pulmonary cryptococcosis, which was subclinical during pregnancy, rapidly worsened to mass-like consolidation at one month after the delivery. Pathohistological examination of the lung specimen showed lung parenchyma infiltration with histiocytes and numerous lymphocytes without granulomatous formations, and a small number of yeast-like organisms consistent with Cryptococcus without capillary involvement. Immunohistochemical staining showed predominance of CD3+ cells and CD4+ cells over CD8+ cells. In addition, GATA3+ cells dominated over T-bet + cells. These data suggested exacerbation of pulmonary cryptococcosis associated with enhancement of Th2 response in the postpartum period.
