Primary undifferentiated embryonal sarcoma of the liver mistaken for hydatid disease

Primary undifferentiated embryonal sarcoma of the liver is a rare tumor with a peak incidence between the ages of 6 and 10 years. We report a case of a primary hepatic undifferentiated embryonal sarcoma arising in a 21-year-old male mistaken for hydatid disease of the liver. The rapid recurrence of this tumor along the site of attempted percutaneous drainage illustrates some important management points regarding this malignancy

Strengthening Ethics: A Faith Perspective on Educational Research

This article discusses ethical guidelines from the viewpoint of the teachings of Islam and, although not ostensibly different, finds parallels in the manner in which ethics could be conceptualised in the context of research in education. It seeks an alignment between ethics from the perspective of being a professional engaged in educational research with a personal significance based on one’s belief, which takes a holistic notion of life. The aims of being ethical researchers seem to be shared in many ways: protection, honesty and integrity. However, there is an added dimension of being accountable to God. The article first locates research within the wider context of Higher Education. Thereafter, to facilitate an understanding of ethics, as viewed from the framework of the Qur’ān, it proceeds to consider the ethical requirements of a university in the West Midlands, England, as a case study to examine the congruence, if any, with some of the ethical teachings of Islam. Based on the preliminary research, this article argues that Muslim researchers in education should be cognisant that their responsibilities are wider. Firstly, they are stewards meaning that the care and well-being of others comes first. Stewardship is both a Biblical and Qur’ānic concept meaning to be guardians. Secondly, by conducting their research in ethical ways, it will mean that they will be performing good deeds. These are meritorious actions rewarded by God. It also clarifies to supervisors and ethics review committees the key principles which might inform the thinking of some researchers from the Muslim community and how their motivations would be ethical

International Consensus Statement on Rhinology and Allergy: Rhinosinusitis

Background: The 5 years since the publication of the first International Consensus Statement on Allergy and Rhinology: Rhinosinusitis (ICAR‐RS) has witnessed foundational progress in our understanding and treatment of rhinologic disease. These advances are reflected within the more than 40 new topics covered within the ICAR‐RS‐2021 as well as updates to the original 140 topics. This executive summary consolidates the evidence‐based findings of the document. Methods: ICAR‐RS presents over 180 topics in the forms of evidence‐based reviews with recommendations (EBRRs), evidence‐based reviews, and literature reviews. The highest grade structured recommendations of the EBRR sections are summarized in this executive summary. Results: ICAR‐RS‐2021 covers 22 topics regarding the medical management of RS, which are grade A/B and are presented in the executive summary. Additionally, 4 topics regarding the surgical management of RS are grade A/B and are presented in the executive summary. Finally, a comprehensive evidence‐based management algorithm is provided. Conclusion: This ICAR‐RS‐2021 executive summary provides a compilation of the evidence‐based recommendations for medical and surgical treatment of the most common forms of RS

Pretherapeutic staging of recurrent laryngeal carcinoma: clinical findings and imaging studies compared with histopathology

OBJECTIVE: To assess the accuracy of preoperative imaging studies and clinical and endoscopic examinations for recurrent laryngeal carcinoma evaluation. STUDY DESIGN AND SETTING: A retrospective comparative study was performed at a university department on 42 recurrent laryngeal carcinomas. Surgical specimens were cut into whole-organ slices. Histologic findings were compared with the findings of the different preoperative diagnostic modalities. RESULTS: The craniocaudal tumor spread was correctly evaluated by endoscopy and imaging studies in 52% and 24%, respectively, and the contralateral tumor spread in 50% and 52%, respectively. The sensitivity, specificity, and accuracy for detection of tumor infiltration of the thyroid was 48%, 88%, and 64% and of the cricoid 47%, 80%, and 67%. The accuracy of recurrent tumor classification (crT) was 50%; most tumors were underclassified. CONCLUSION: The inadequately evaluated tumor spread and the inadequately classified recurrent tumors were underestimated and underclassified in most cases, respectively
