Objective: To determine which otolaryngology residency programs have social media platforms and to review which programs are utilizing platforms to advertise virtual open houses and virtual subinternships for residency applicants. Study Design: Cross-sectional study. Setting: The study was conducted online by reviewing all accredited otolaryngology residency programs in the United States participating in the Electronic Residency Application Service. Methods: Otolaryngology residency programs were reviewed for social media presence on Instagram, Twitter, and Facebook. Social media posts were evaluated for virtual open houses and virtual subinternships. Residency websites and the Visiting Student Application Service were evaluated for the presence of virtual subinternships. All data were collected between September 5, 2020, and September 9, 2020. This study did not require approval from the University of Alabama at Birmingham Institutional Review Board for Human Use. Results: Among 118 otolaryngology residency programs, 74 (62.7%) participate on Instagram, 52 (44.1%) participate on Twitter, and 44 (37.3%) participate on Facebook. Fifty-one Instagram accounts, 20 Twitter accounts, and 4 Facebook accounts have been created during 2020. Forty-two (36%), 30 (25.4%), and 15 (13%) programs are promoting virtual open houses on Instagram, Twitter, and Facebook, respectively. Two programs on the Visiting Student Application Service offered virtual subinternships. Seven residency program websites offered virtual subinternships. Nine, 6, and 1 program offered virtual subinternships on Instagram, Twitter, and Facebook, respectively. Conclusion: This study demonstrates that social media presence on Instagram and Twitter among otolaryngology residency programs has substantially grown in 2020 at a higher rate compared to previous years. These data suggest that otolaryngology residency programs are finding new ways to reach out to applicants amid an unprecedented type of application cycle due to the challenges presented by COVID-19. Many programs are advertising virtual open houses via social media platforms to connect with applicants, and a few programs are offering virtual subinternships to replace traditional subinternships.
A partial or complete defect of the cerebellar vermis may occur sporadically or as a component of the Dandy-Walker syndrome, the Dandy-Walker variant, Down's syndrome, or Joubert-syndrome. We identified a defect of the cerebellar vermis in nine fetuses on routine antenatal sonographic studies. In five of the nine fetuses other abnormalities, including central nervous system and non-central nervous system lesions were identified. Three of these five fetuses died and two infants have remained well on follow-up. Four of nine fetuses (or infants) had no other abnormalities and have remained well on follow-up at 8 weeks to 4 years of age. Although cases of fatal and serious nonfatal outcomes have been reported by other investigators, in this small series the finding of an isolated inferior vermian defect was associated with a good prognosis.
Background Low-grade gliomas cause significant neurological morbidity by brain invasion. There is no universally accepted objective technique available for detection of enlargement of low-grade gliomas in the clinical setting; subjective evaluation by clinicians using visual comparison of longitudinal radiological studies is the gold standard. The aim of this study is to determine whether a computer-assisted diagnosis (CAD) method helps physicians detect earlier growth of low-grade gliomas. Methods and findings We reviewed 165 patients diagnosed with grade 2 gliomas, seen at the University of Alabama at Birmingham clinics from 1 July 2017 to 14 May 2018. MRI scans were collected during the spring and summer of 2018. Fifty-six gliomas met the inclusion criteria, including 19 oligodendrogliomas, 26 astrocytomas, and 11 mixed gliomas in 30 males and 26 females with a mean age of 48 years and a range of follow-up of 150.2 months (difference between highest and lowest values). None received radiation therapy. We also studied 7 patients with an imaging abnormality without pathological diagnosis, who were clinically stable at the time of retrospective review (14 May 2018). This study compared growth detection by 7 physicians aided by the CAD method with retrospective clinical reports. The tumors of 63 patients (56 + 7) in 627 MRI scans were digitized, including 34 grade 2 gliomas with radiological progression and 22 radiologically stable grade 2 gliomas. The CAD method consisted of tumor segmentation, computing volumes, and pointing to growth by the online abrupt change-of-point method, which considers only past measurements. Independent scientists have evaluated the segmentation method. In 29 of the 34 patients with progression, the median time to growth detection was only 14 months for CAD compared to 44 months for current standard of care radiological evaluation ( p < 0.001). Using CAD, accurate detection of tumor enlargement was possible with a median of only 57% change in the tumor volume as compared to a median of 174% change of volume necessary to diagnose tumor growth using standard of care clinical methods ( p < 0.001). In the radiologically stable group, CAD facilitated growth detection in 13 out of 22 patients. CAD did not detect growth in the imaging abnormality group. The main limitation of this study was its retrospective design; nevertheless, the results depict the current state of a gold standard in clinical practice that allowed a significant increase in tumor volumes from baseline before detection. Such large increases in tumor volume would not be permitted in a prospective design. The number of glioma patients ( n = 56) is a limitation; however, it is equivalent to the number of patients in phase II clinical trials. Conclusions The current practice of visual comparison of longitudinal MRI scans is associated with significant delays in detecting g...
