Physical Examination and Appendiceal Signs During Pregnancy.

The clinical diagnosis of acute appendicitis is challenging as patients present with an array of objective and subjective symptoms early or late in the disease course. Ultrasound is routinely performed in all patients with suspected acute appendicitis. Equivocal test results frequently require further assessments using other imaging techniques that are limited in scope during pregnancy because of issues involving safety, availability, and accessibility. Physical examination diagnostic signs in acute appendicitis during pregnancy have not been well studied. Studies failed to describe, standardize, or correlate the technique used to the pathologic disease process. Therefore, gaps remain in current knowledge regarding the usefulness and application of these tests during the physical examination. Improvement in diagnostic acumen is critically important, particularly in cases where there remains diagnostic uncertainty because of equivocal imaging results. This article reviews signs used to diagnose patients with acute appendicitis using a pathophysiologic approach based on visceral and cerebrospinal nerve pathways to explain the mechanism for a positive test result. It also suggests a framework to study them further to better understand their role, if any, in clinical practice.

How to Classify, Teach, and Learn Ophthalmic Eponyms.

Introduction There are limited educational studies on effective ways to teach and learn medical eponyms. While there is no consensus on how to best address this issue, developing novel strategies to teach medical eponyms has become critical in many branches of medicine, including ophthalmology.  Materials & Methods An ophthalmologic eponymic database was created using eight source texts (e.g., books, encyclopedias, and dictionaries) and included the year the eponym was introduced, related name, nationality, specialty, and the eponym's description. PubMed database with a Medical Subject Headings (MeSH) keyword for "eponym" and "eye" and "ophthalmology" and a Google search for a combination of related keywords was also performed. A careful biographical search was conducted for each name in the second phase to obtain further biographical details. Inclusion criteria for eponyms in the dataset were: i) named after at least one person, ii) identified as a specific medical term in the literature, iii) related to any field of medicine. Names derived from art, history, mythology, patient, family, chemistry, botany (or other fields outside of medicine) were excluded. The three authors independently screened to eliminate duplicated names and ensure eligible names met inclusion and exclusion criteria. Results A total of 1,257 unique ophthalmologic eponyms representing 8.8% of 14,332 medical eponyms were identified. Three-hundred fifty-one of 743 (47.2%) eponyms were named after ophthalmologists representing 36 countries. The United States of America and Germany comprised the largest fraction of nationalities (40.2%), not necessarily representing their birthplace. Signs, syndromes, and diseases composed the largest category (45.8%) of eponymous ophthalmologic names. Discussion The current volume of eponymous names impedes the ability of a learner to retain this information. Classifying eponyms based on form, intention, or function, provides a more refined method for placing eponyms in their respective categories. Teaching eponyms by enumerating their historical content, demonstrating the correct performance of the eponym, assessing the technique, and providing feedback, affords the learner a more fruitful and meaningful learning experience. Understanding the context of the signs, syndrome, or techniques further allows the learner to gain insights into the clinical application of eponyms in diagnostic decision-making. Conclusion The teaching model proposed incorporates key aspects that may facilitate retention and recall of the eponymous name. The model includes imparting historical knowledge about the person who described the sign, technique, or process; demonstrating the correct procedure as originally reported; and coaching to ensure that the appropriate skill is mastered. Before abandoning eponyms, it is first necessary to understand their efficacy, effectiveness, usefulness, and role in clinical medicine.

Eponymous signs in toxicology and poisoning in the nineteenth and early twentieth centuries.

Toxicology emerged as an independent discipline in the early nineteenth century and has been aided by the development of numerous sophisticated tests that allow physicians and scientists to identify, quantify, and quantitate elements, chemicals, compounds, and toxins and to sort them into their component parts. These developments also contributed to enrich toxicological terminology with many new terms and eponyms in particular. Eponyms are ascribed to a variety of phenomena including attributing, in many cases, to the person who first identified or described a particular phenomenon and are named for the variety of findings found during the medical, surgical, pathological, or laboratory evaluation. Focusing on eponymous signs caused by poisons and toxins, the purpose of this paper is to honor the eponymous persons who first discovered, described, or more fully elaborated the finding. Nearly 30 associated eponyms have been identified in the literature, half of which were named for persons (e.g., Anstie sign, Billard sign, Blyth sign, Burton sign/line, Corrigan sign, Hertoghe sign, Peary sign). We believe that they are important to learn as they impart an in-depth appreciation of their role and application during the clinical examination. Knowledge of the person's biographical accomplishment(s) and character imparts a personalized and humane qualities to these signs from a medico-historical perspective. Understanding these signs and how to recognize them provides a method applying the bedside clinical examination to further support clinical suspicion or diagnose disease.

Reimagining the Terms Mongolian Spot and Sign.

The term "Mongolian Spot" rather than the preferred descriptive name congenital dermal melanocytosis (CDM) continues to be used despite compelling objections to the contrary. Terms that stigmatize a culture, region, people, country, communities, and ethnic group should be replaced by their more descriptive counterparts. Herein, we clarify terminology, discuss the historical significance, and provide a recommendation about naming this disease.
