Assessment equity for remote multilingual Australian Aboriginal students through the lens of Sustainable Development Goals.

PURPOSE: The Foundations of Early Literacy Assessment - Northern Territory (FELA-NT) was funded, developed, and implemented as part of a strategy designed to address the English literacy learning needs of the Northern Territory's Aboriginal student population. In this paper we question whether the FELA-NT English literacy learning benchmarks are representative of remote and very remote Aboriginal students since many speak English as an Additional Language (EAL) or Dialect (EAD). RESULT: Using a new data set of scores from 72 Aboriginal students from remote, very remote, and outer-regional communities on the FELA-NT, we demonstrate that it is the student's experience with Standard Australian English, not their remoteness, that impacts their early literacy development. CONCLUSION: We use this example to illustrate how current practices and policies homogenise the Australian Aboriginal student population, silencing linguistic diversity in the process. We call for clinical practitioners and educators to shift their practices to assessments and tools that recognise children and youths' diverse linguistic skills and pathways. We talk about what empowerment, participation, and inclusion might really mean in current Australian educational and clinical contexts. We argue here that we need to fundamentally rethink how we work with children with diverse language and literacy knowledge, skills, and backgrounds if we are to reduce inequalities (SDG 10), honour quality education (SDG 4), and support sustainable communities (SDG 11).

Localized Metastatic Recurrence of HCC following Distal Extremity Trauma: Bone Scintigraphy and Anatomicopathological Correlation.

Hepatocellular carcinoma (HCC) is the most common type of liver cancer, with a poor median survival when left untreated. Extrahepatic metastases involving musculoskeletal tissues typically present with concomitant nonosseous metastases at the time of diagnosis. A 61-year-old male on 1-year remission, following transarterial chemoembolization of a 2.3-cm hepatic HCC 1 year before, presented with a 2-month history of left wrist pain and swelling after falling on an outstretched hand. Computed tomographic scan revealed diffuse osteolytic lesions localized in left hand and distal forearm, associated with equivocal diffuse activity on bone scan. Subsequent surgical debridement revealed metastatic hepatocellular carcinoma.

Experience with a Perfusion-Only Screening Protocol for Evaluation of Pulmonary Embolism During the COVID-19 Pandemic Surge.

The purpose of this study was to evaluate a pulmonary embolism (PE) perfusion-only screening (POS) protocol introduced during the coronavirus disease 2019 (COVID-19) pandemic surge. Subjects without dense parenchymal lung opacities were studied; those with less than 1 segmental perfusion defect were considered to have no PE, whereas those exhibiting 1 or more defects were indeterminate, mandating additional examinations to determine the final diagnosis. Methods: We analyzed demographic information, clinical data, imaging findings, and follow-up data from the electronic records of COVID-19 patients who underwent lung scintigraphy during the 60-d study period. Results: In total, 53 studies were performed on 17 COVID-19-positive and 36 COVID-19-negative patients. The POS protocol efficiently excluded PE in 79% of cases; the remaining 21%, indeterminate for PE, were generally referred for alternative testing or were directly anticoagulated. In patients with negative POS results, there was a very low mortality before hospital discharge (1/42) and normal results on follow-up studies (6/6). Conclusion: The POS protocol, implemented during the COVID-19 surge, efficiently and safely excluded PE in 79% of patients.

Diagnostic Performance of Pulmonary Embolism Imaging in Patients with History of Asthma.

Asthma and pulmonary embolism (PE) can present with overlapping symptoms, and distinguishing between these 2 conditions can be challenging. Asthma may limit imaging for PE because of either worsened ventilation defects on ventilation-perfusion scanning (VQ) or increased motion artifacts on CT pulmonary angiography (CTPA). Methods: We identified adults evaluated for PE with VQ or CTPA from 2012 to 2016. Patients with chronic lung disease (other than asthma) were excluded. Studies were classified as negative, positive, or nondiagnostic. Follow-up of negative cases was reviewed to determine the rate of repeat exams (within 1 wk) and the false-negative rate (defined as diagnosis of venous thromboembolism within 90 d). Results: We reviewed 19,412 adults (aged 52 ± 18 y, 70% women) evaluated for PE (60% with VQ, 40% with CTPA); 23% had a history of asthma. Nondiagnostic results were comparable for those with and without asthma for both VQ (asthma, 3.3%; nonasthma, 3.8%; P = 0.223) and CTPA (asthma, 1.6%; nonasthma, 1.5%; P = 0.891). A history of asthma was not associated with a higher rate of repeat exams after negative imaging for VQ (asthma, 1.9%; nonasthma, 2.1%; P = 0.547) or CTPA (asthma, 0.6%; nonasthma, 0.6%; P = 0.796), nor was a history of asthma associated with a higher false-negative rate for VQ (asthma, 0.4%; nonasthma, 0.9%; P = 0.015) or CTPA (asthma, 1.9%; nonasthma 1.5%; P = 0.347). Conclusion: A history of asthma in the preceding 10 y was not associated with impaired diagnostic performance of PE imaging for either VQ or CTPA.

Unilateral Absence of the Basal Ganglia on 123I-Ioflupane DaTScan.

This 33-year-old man presented with hemorrhagic stroke manifesting with left hemiparesis and right ptosis. Angiography revealed no patent carotids. The anterior and middle cerebral arteries were filling collaterally through the posterior vertebrobasilar pathway. The presumptive diagnosis was moyamoya disease. The etiology of the bleeding was right basilar tip aneurysm that subsequently had partial coil placement. Months later, the neck of the aneurysm perforated and second coiling was performed. Later on follow-up, patient developed left hand tremor. A radionuclide DATscan revealed total absence of right-sided basal ganglia activity. A possible etiology was occlusion of the middle cerebral artery's lenticulostriate branches.

Imaging for Pulmonary Embolism in Sickle Cell Disease: A 17-Year Experience.

Sickle cell disease, a complex disorder with known pulmonary complications, has the potential to confound the diagnosis of pulmonary embolism. We hypothesized that when the choice of imaging is guided by chest radiographic results, CT pulmonary angiography (CTPA) and ventilation-perfusion (V/Q) scintigraphy have comparable diagnostic performance in sickle cell disease. Methods: A retrospective cohort of adults with sickle cell disease who were imaged for suspected pulmonary embolism with either CTPA or V/Q, from 2000 to 2016 at our institution, was established. To reduce radiation exposure, our practice recommends V/Q for stable patients with normal chest radiographs. Results of index pulmonary embolism imaging, 90-d follow-up, and results of chest radiography were recorded. Results: Two hundred forty-five adults with sickle cell disease comprised the cohort. The mean age (±SD) was 33 ± 10.5 y, and 58% (141) were men. Index imaging was V/Q in 62.9% (n = 154) and CTPA in 37.1% (n = 91). Chest radiographs, performed in 96.3% (n = 236), were normal in 72.9% (n = 172). Imaging results for pulmonary embolism were negative in 88.2% (n = 216), positive in 4.1% (n = 10), and indeterminate in 7.8% (n = 19) with no difference between V/Q and CTPA (P = 0.63). Reimaging within 90 d occurred in 9.8% (n = 24), 14.7% (20/136) after initial V/Q, and 5% (4/109) after initial CTPA (P = 0.08). Reimaging revealed a pulmonary embolism diagnosis after negative/indeterminate results in 0.7% (1/149) of V/Qs and 1.2% of (1/86) CTPAs (P = 0.69). Over the 17-y study period, 47% (114/245) underwent repeated imaging, and 11% (27/245) were diagnosed with pulmonary embolism at least once. Conclusion: In sickle cell disease patients with suspected pulmonary embolism, positive imaging rates were low for any given clinical presentation, but 11% of the cohort was diagnosed with pulmonary embolism over the 17-y study period. CTPA and V/Q performed comparably for pulmonary embolism diagnosis when the choice of imaging was guided by results of chest radiography. Hence, V/Q is a reasonable first choice for sickle cell disease patients with normal chest radiographs.

Performance of Low-Dose Perfusion Scintigraphy and CT Pulmonary Angiography for Pulmonary Embolism in Pregnancy.

BACKGROUND: The symptoms of normal pregnancy overlap those of pulmonary embolism (PE). Limited literature suggests that low-dose perfusion scanning (LDQ), which yields lower maternal-fetal radiation exposure than CT pulmonary angiography (CTPA), performs well in excluding PE in pregnant patients. METHODS: We performed a retrospective cohort study of sequential pregnant women who underwent imaging for PE with LDQ or CTPA between 2008 and 2013 at Montefiore Medical Center. Our practice recommends LDQ for patients with negative results on chest radiographs. Patients were categorized according to initial imaging modality, and a subgroup analysis was performed in patients with asthma. The primary outcome was the negative predictive value (NPV) of imaging determined by VTE diagnosis within 90 days. RESULTS: Of 322 pregnant women (mean age, 27.3 ± 6.3 years), initial imaging was positive for PE in 2.7% (6 of 225) of LDQs and 4.1% (4 of 97) of CTPAs, negative in 88.0% (198 of 225) of LDQs and 86.6% (84 of 97) of CTPAs, and indeterminate/nondiagnostic in 9.3% (21 of 225) of LDQs and 9.3% (9 of 97) of CTPAs (P = .79). Ten patients (3.1%) were treated for PE. The NPV was 100% for LDQ and 97.5% for CTPA. Subgroup analysis of patients with asthma (23.9% of this population) revealed a high likelihood of a negative study in the LDQ and CTPA groups (74.1% and 87.0%, respectively) and 100% NPV for both modalities. CONCLUSIONS: PE is an uncommon diagnosis in pregnancy. LDQ and CTPA perform well, with less maternal-fetal radiation exposure with LDQ. Therefore, when available, LDQ is a reasonable first-choice modality for suspected PE in pregnant women with a negative result on chest radiograph.
