MeSH terms: Case Reports

A 45-year-old female presented with recurrent biliary pain, fever, anorexia and weight loss of 3 months duration. She was on highly active antiretroviral therapy for underlying human immunodeficiency virus infection for the past 5 months. Clinical examination revealed a 3-cm firm hepatomegaly. Investigations suggested mild anaemia, elevated erythrocyte sedimentation rate, deranged liver function tests, Mantoux test of 25 mm and CD4 count of 417 cells μl-1. Ultrasonography revealed mild central intrahepatic biliary radical dilatation with a dilated common bile duct and multiple periportal and peripancreatic lymph nodes. Ultrasound-guided fine needle aspiration cytology (FNAC) from the periportal lymph node was performed twice. Both were reported as only bloody aspirate. The patient developed an erythematous tender skin nodule at the site of insertion of the FNAC needle 15 days after the second FNAC procedure. An excision biopsy of the nodule showed ill-formed epithelioid cell granulomas with acid-fast bacilli, indicating tuberculosis. The patient was started on antitubercular therapy with complete response.
A Rare and Unexpected Reason for Unilateral Epistaxis: Nasal Septal Schwannoma
Authors: Alper Yenigun, Yasin Kulaksiz, Tugce Esen Kiran, Erol Senturk, Fadlullah Aksoy, Orhan Ozturan

MeSH terms: Case Reports

Nasal septal schwannoma is a rare tumor. It causes complaints such as nasal congestion, nosebleeds, and headaches. There are many diseases such as nasal polyps, antrochoanal polyp, chronic rhinosinusitis, concha bullosa, inverted papilloma, and retention cyst with schwannoma diagnosis. The diagnosis is made histopathologically, and the treatment is surgery. In this case report, we presented a male patient with septal schwannoma who had nasal obstruction for a year and reviewed the last 20 years of literature on nasal schwannoma.
Investigating the measurement of academic resilience in Aotearoa New Zealand using international large-scale assessment data

Keywords: academic resilience measurement, academic resilience operationalisation, international large-scale assessment, protective factors, socioeconomic status

Academic resilience captures academic success despite adversity and thus is an important concept for promoting equity within education. However, our understanding of how and why rates of academic resilience differ between contexts is currently limited by variation in the ways that the construct has been operationalised in quantitative research. Similarly, comparing the strength of protective factors that promote academic resilience is hindered by differing approaches to the measurement of academic resilience. This methodological variation has complicated attempts to reconcile disparate findings about academic resilience. The current study applied six commonly used operationalisations of academic resilience that combined different thresholds of high risk and high achievement, to three international large-scale assessments, to explore how these different operationalisations impacted the findings produced. The context of Aotearoa New Zealand was chosen as a case study to further academic resilience research within this context and investigate how academic resilience manifests in an education system with relatively high levels of average achievement alongside low levels of educational equity. Within international large-scale assessment datasets, prevalence rates differed markedly across subject areas, grade levels, and collection cycles, as a function of the measure of academic resilience employed, while the strength of protective factors was more consistent. Thresholds that were norm-referenced produced more consistent findings across the different datasets compared to thresholds that were criterion-referenced. High levels of missing data prevented the analysis of some datasets, and differences in the way that key constructs were measured undermined the comparability of findings across international large-scale assessments. The findings emphasise the strengths and limitations of utilising international large-scale assessment data for the study of academic resilience, particularly within the Aotearoa New Zealand context. Furthermore, the study highlights that researchers' methodological decisions have important impacts on the conclusions drawn about academic resilience.

Ischemic Stroke of the Artery of Percheron with Normal Initial MRI: A Case Report
Authors: Guillaume Cassourret, Bertrand Prunet, Fabrice Sbardella, Julien Bordes, Olga Maurin, Henry Boret
Journal: Case Rep Med (2010)
MeSH terms: Case Reports

The artery of Percheron is a solitary trunk representing an uncommon anatomic variant that provides bilateral arterial supply to the paramedian thalami and the rostral midbrain. Occlusion of this artery results in bilateral thalamic and mesencephalic infarctions. The clinical diagnosis is difficult because the complex anatomy causes large clinical variability. We report a case of a comatose patient with normal early head-computed tomography and magnetic resonance imaging. A bilateral paramedian thalamic infarct due to an occlusion of the artery of Percheron was revealed two days later by a new head computed tomography. To our knowledge, this is the first report in the literature of a symptomatic patient presenting an acute Percheron stroke with normal early brain magnetic resonance imaging. Our case indicates that a normal initial magnetic resonance imaging cannot formally eliminate the diagnosis of acute stroke of the artery of Percheron. We discuss the causes of noncontributive brain magnetic resonance imaging at the onset of this acute Percheron stroke and the alternative diagnosis and therapy methods.
