The case for case reports

The value of case reports in diagnostic radiography

OBJECTIVE

- This paper sought to explore the value of case reports in diagnostic radiography with regards to current usage, relevance to evidence-based radiography, and educational benefits.

KEY FINDINGS

Case reports are short accounts of novel pathologies, trauma or treatment with a critical review of relevant literature. Examples within diagnostic radiography include the appearances of COVID-19 alongside examination-level scenarios involving image artefacts, equipment failure and patient incidents in radiology. With greatest risk of bias and lowest generalisability, they are considered as low-quality evidence with generally poor citation rates. Despite this, there are examples of significant discoveries or developments initiated with case reports with important patient care implications. Furthermore, they offer educational development for both reader and author alike. Whereas the former learns about an unusual clinical scenario, the latter develops scholarly writing skills, reflective practice and may generate further, more complex, research. Radiography-specific case reports could capture the diverse imaging skills and technological expertise currently under-represented in traditional case reports. Potential avenues for cases are broad and may include any imaging modality where patient care or safety of other persons may illicit a teaching point. This encapsulates all stages of the imaging process, before, during and after patient interaction.

CONCLUSION

Despite being low-quality evidence, case reports contribute to evidence-based radiography, add to the knowledge base, and foster a research culture. However, this is contingent upon rigorous peer-review and adherence to ethical treatment of patient data.

IMPLICATIONS FOR PRACTICE

With the drive to increase research engagement and output at all levels in radiography (student to consultant), case reports may act as a realistic grass-root activity for a burdened workforce with limited time and resources.

Thyroid abscess due to ingested fish bone, endoscopic, and surgical approach: a case presentation

Introduction

Thyroid abscesses are a rare septic complication as the thyroid is innately resistant to infection.

Case presentation

Here, we present a case of a 49-year-old female with history of accidental ingestion of a fish bone, subsequent perforation of the esophagus, and thyroid abscess formation.

Management approach consisted of imaging of the gland followed by upper gastrointestinal endoscopy and surgical thyroidotomy with fish bone extraction.

Conclusion

In this case presentation, we highlight the pathophysiology behind thyroid abscess along with review of offered lines of management of this disease from imaging and procedures of diagnosis to treatment approach of source control by both surgical and conservative approach.

History and Development of TCM Case Report in a Real-World Setting

Objective. The medical record of Chinese medicine is a miniature of the theoretical system of traditional Chinese medicine (TCM), with a time-honored history in a real-world setting and a firm place in medicine. In modern times, people have emphasized the value and standardization of TCM cases. The aim of this study was to explore the historical origins and developments of TCM case records. Methods. A chronological narrative style was used to divide the development history of TCM case records into early (1600 BC–220 AD), middle (220–1911 AD), and modern periods (1912–till now). The historical context of the origin and development of TCM case records was analyzed through the evolution of the format and content of the case recording files with the specific documents and distinctive cases. Results. From the early to middle period, the development of TCM case record had experienced four periods: the budding, blossoming, maturity, and heyday. In modern times, they presented the following characteristics: A, the establishment and development of the discipline of TCM medical records; B, the standardization of the writing format of TCM medical records; C, a large number of books concentrating on recording and studying TCM medical records, especially those of prestigious veteran TCM doctors; D, the proliferation of TCM case reports published in journals; E, the establishment of TCM medical records databases and application platforms integrating computer programs and artificial intelligence; F, many reporting guidelines have been developed in order to improve the reporting quality of case report in TCM. Conclusions. The study analyzed and illustrated the characteristics of TCM case records of different dynasties in terms of writing content and format. TCM case record is a relatively young discipline in spite of its ancient origins. TCM case records still have far-reaching significance for the inheritance and development of TCM theory and clinical experience. From the wisdom of history, its positive impact has just been revalued to be validated and it will continue to develop.

Writing scientific case reports for top-line journals

The venerable clinical case report has been largely reduced to the status of commodity in the present age of dedicated case report journals. Top-line clinical journals may discourage or even refuse to accept clinical case reports due to their potential adverse effect on the impact factor of the journal. But while the traditional clinical case report, that presents a case history and attempts to extrapolate a lesson from it, may have fallen out of favor, there remains a need for astute clinical observations that serve to stimulate the generation of hypotheses and may lead, ultimately, to medical breakthroughs. Clinicians are very much capable of employing scientific reasoning when approaching an unusual clinical situation. By remaining up to date with the literature, and determining, at the outset of the case, what lessons may be learned from it, they can formulate a scientific approach, using clinical methods, to result in meaningful contributions to the literature in top-line journals.

A possible link between intracranial lipomas and localization-related relapses in multiple sclerosis

Intracranial lipomas are congenital malformations representing less than 0.5% of intracranial tumors. They are found incidentally and are asymptomatic in the majority of patients. Here we present three patients with Multiple sclerosis (MS) and intracranial lipomas (IL). The patients showed increased flares and burden of disabling and worsening MS symptoms with cognitive, neurovestibular dysfunction, and gait alterations associated with the localization of the Lipoma. The parenchyma near the Lipomas showed areas of demyelination and atrophy. We postulate that the location and content of the Lipomas may participate in the pathophysiology of MS symptoms in these patients. We conclude that in concurrent IL and MS, the lipomas localization may provoke incapacitating relapses.

Promoting scholarship in a community-based internal medicine residency

The University of South Dakota Sanford School of Medicine Internal Medicine residency implemented a program to enhance scholarship among residents. This residency is part of a small Mid-Western community-based school.

Background: A Director of Research was hired and developed a structured approach consisting of: 1. Independent study regarding research methods and statistical testing and 2. Mentoring of residents and faculty in scholarly pursuits starting in the first months of residency.

Methods: Scholarship for two cohorts of residents for years July 2011–2014 and January 2014–2017 were followed. Products included papers accepted/published and papers accepted/presented at national or international meetings.

Results: 7 (14.8%) of 47 residents in the first cohort published 12 papers (0.25 papers/resident) with 18 faculty as co-authors (1.5/paper). 20 (43.4%) of 46 residents in the second cohort (structured program) published 39 papers (0.85 papers/resident) with 80 faculty as co-authors (2.1/paper). The difference in papers was significant by chi-square analysis.

Conclusion: A structured program requiring independent study in conjunction with individualized mentoring of scholarship starting early in the first postgraduate year was successful in significantly increasing the scholarly activity of our community-based internal medicine residents and faculty. With this program, the percentage of residents publishing exceeds national statistics recently reported.

Case report classics in otolaryngology – head and neck surgery: citation analysis

Objectives

To analyse publication and citations trends of case reports within otolaryngology – head and neck surgery literature, with specific attention to the most-cited reports.

Study design

Database query.

Methods

Web of Science was searched for article type ‘case reports’ published in the leading otolaryngology – head and neck surgery journals since 1945. Variables including publication dates, citation dates and numbers, author, author number, and others were recorded and analysed for trends. The reports with the most citations (classics) were further studied.

Results

Of nearly 67 000 published articles in leading otolaryngology – head and neck surgery journals, the overall number of case reports as a percentage of the total has substantially decreased over time. A total of 110 case report classics were identified for which citations have increased.

Conclusion

Although the case report may not be worthy of its tarnished record, declining trends in publication suggest a limited future for this valuable research and educational resource.

New journals for publishing medical case reports

Because they do not rank highly in the hierarchy of evidence and are not frequently cited, case reports describing the clinical circumstances of single patients are seldom published by medical journals. However, many clinicians argue that case reports have significant educational value, advance medical knowledge, and complement evidence-based medicine. Over the last several years, a vast number (∼160) of new peer-reviewed journals have emerged that focus on publishing case reports. These journals are typically open access and have relatively high acceptance rates. However, approximately half of the publishers of case reports journals engage in questionable or "predatory" publishing practices. Authors of case reports may benefit from greater awareness of these new publication venues as well as an ability to discriminate between reputable and non-reputable journal publishers.
