The purpose of this statement is to provide guidelines to assist hospital credentialling committees in their task of granting privileges to perform gastrointestinal endoscopy. Endoscopy of the gastrointestinal tract has evolved over the past 30 years as a potent tool to assist in the evaluation, diagnosis and therapy of patients with gastrointestinal tract disorders. Although gastrointestinal endoscopy was initially developed as a purely diagnostic tool, the development of therapeutic endoscopic techniques has dramatically expanded the role of gastrointestinal endoscopy, frequently to a therapeutic one. In setting guidelines for training and credentialling one must recognize that, excluding flexible sigmoidoscopy, endoscopists should be well trained in therapeutic endoscopy.

Informed consent has undergone a transformation from an ethical concept to a legal doctrine. It is based on the ethical principles of self-determination and autonomy. Over the past several years, courts have established physician liability based on the failure to obtain adequate informed consent. It is the duty of all gastrointestinal endoscopists to obtain legally adequate informed consent before performing any endoscopic procedure.

Vitamin A (retinol) is one of the key elements for regulating the immune response and controls the division and differentiation of epithelial cells of the mucous membranes of the bronchopulmonary system, gastrointestinal tract, urinary tract, eyes, etc. Its significance in the context of the COVID‑19 pandemic is difficult to overestimate. However, a number of studies conducted in the past have associated the additional intake of vitamin A with an increased risk of developing cancer, as a result of which vitamin A was practically excluded from therapeutic practice in developed countries. Our review highlights the role of vitamin A in maintaining human health and the latest data on its effect on the development mechanisms of somatic pathology.

Hypertext Markup Language

This article focuses on the role of past standards stories and how they are deployed strategically in ways that shape the process of standards creation. It draws upon an ethnographic study over multiple years of standards meetings, discussions, and online activity. Building on existing work that examines how standards are shaped by stories, this study follows the development of Augmented Reality Markup Language and maps how the story of Hypertext Markup Language (HTML) became the key story that actors utilized and debated to push for participation, agreement, and material development of the standard. The authors present several different ways the recurring HTML story was effective at various points in the process as a diagnostic tool, promissory future, empirical evidence, and confidence building measure. Understanding these strategic deployments serves as an empirical example of how recurring stories of the past can shape standards development. These mappings illustrate how standards can be built on past standards sociologically as well as technologically and also broadens our theoretical tools for understanding the importance of stories in the sociology of standards.

Rapid Clearance

Over the past decade, multiple clinical reports have demonstrated that the use of propofol sedation for gastrointestinal endoscopy by gastroenterologists and trained endoscopy nurses is safe and effective in appropriately selected patients. Proposed benefits of propofol sedation include rapid onset of action, improved patient comfort and rapid clearance, as well as prompt recovery and discharge from the endoscopy unit. As a result of medical evidence, a number of international professional societies have endorsed the use of propofol in gastrointestinal endoscopy. In Canada, no formal guidelines currently exist. In the present article, the Clinical Affairs Committee of the Canadian Association of Gastroenterology presents a position statement, incorporating updated information on the use of propofol sedation for endoscopy in adult patients.

ABSTRACT Autism spectrum disorder (ASD) is a remarkably complex disorder influenced by both genetic and environmental factors. Numerous microbial diversity surveys conducted over the past decade have attempted to link specific ASD biomarkers to gastrointestinal tract disturbances, but results generated across cohorts and studies remain inconsistent. This commentary discusses multidirectional interactions between the host, the microbiome, and external factors germane to autism. Recent studies posit the heritability of the gut microbiome itself, confounding attempts to discern heritable from nonheritable effectors in neurodevelopmental disorders. Elucidating the ever-evolving gut microbiome’s role in modulating the ASD phenotype will most certainly require new experimental methodologies and designs. In a recent paper published in mSystems (J. Fouquier, N. Moreno Huizar, J. Donnelly, C. Glickman, et al., mSystems e00848-20, 2021, https://doi.org/10.1128/mSystems.00848-20), the authors describe a web of interactions by collecting samples longitudinally, analyzing cross-sectional cohorts, and recording nonbinary phenotypic measurements.

Introduction The earliest gastrointestinal (GI) endoscopies were performed in the late 1880s by using rigid instruments to examine the esophagus and rectum. The semiflexible gastroscope was developed in the early 1930s by Schindler and Wolf, and fiberoptic endoscopes were popularized in the late 1960s and early 1970s. The first small-diameter instrument used for esophagogastroduodenoscopy (EGD) in a child was a fiberoptic bronchoscope. Video endoscopy has only developed over the past 2 decades, with the first mass-produced video instruments introduced in the 1980s. Parts or all of the procedure can be recorded for later review. Pediatric GI endoscopists can perform most of the endoscopic techniques of their adult counterparts. The referring physician and endoscopist should be familiar with the risks and benefits of endoscopy as well as clinical situations in which it is most useful. Personnel Specially trained pediatric endoscopy assistants are an important component of the endoscopy team. Preprocedure anxiety may be reduced by a physician, nurse, or play therapist explaining the procedure to the patient. One assistant can hold and reassure the child throughout the procedure while a second can help to obtain and process tissue and assist with other equipment and patient monitoring. Physicians performing GI endoscopy on infants and children should have completed a pediatric gastroenterology fellowship or have experience with pediatric gastrointestinal diseases and adequate training in pediatric endoscopy.

Over the past five years (1973–78) the Canadian educational model for occupational therapy has undergone considerable revision. The role of the Canadian Association of Occupational Therapists in this development is reviewed. Implications for the 1980's are discussed in light of the recent Symposium on Occupational Therapy (Toronto, 1978). Data augmenting this review are presented in tabular form.

AbstractThe authors evaluated the role of endoscopic techniques in the diagnosis and in the potential treatment of neuroendocrine tumors (NET) localized in the gastro-entero-pancreatic system, on the basis of their experience and of the international literature. NET are rare tumors that arise from neuroendocrine cells of the gastrointestinal tract and pancreas. It is a possibility that both the digestive endoscopy and EUS play an important role in the diagnosis, staging and surveillance of this disease. In some cases, especially in the early stages, surgical endoscopy allows the treatment of such tumors.

The Many

The role of electron microscopy and associated techniques is assured in diagnostic pathology. At the present time, most of the progress has been made on tissues examined by transmission electron microscopy (TEM) and correlated with light microscopy (LM) and by cytochemistry using both plastic and paraffin-embedded materials. As mentioned elsewhere in this symposium, this has revolutionized many fields of pathology including diagnostic, anatomic and clinical pathology. It began with the kidney; however, it has now been extended to most other organ systems and to tumor diagnosis in general. The results of the past few years tend to indicate the future directions and needs of this expanding field. Now, in addition to routine EM, pathologists have access to the many newly developed methods and instruments mentioned below which should aid considerably not only in diagnostic pathology but in investigative pathology as well.
