Dizziness is the quintessential symptom presentation in all of clinical medicine. It is a common reason that patients present to a physician. This chapter provides background information about the vestibular system, then reviews key aspects of history-taking and examination of the patient, then discusses specific disorders and common presentation types. Throughout the chapter the focus is on neurologic and vestibular disorders. Normal vestibular anatomy and physiology are discussed, followed by recommendations for history-taking and the physical examination. Specific disorders that cause dizziness are explored, along with common causes of non-specific dizziness. Common presentations are discussed, including acute severe dizziness, recurrent attacks, and recurrent positional vertigo. Finally, the chapter looks at laboratory investigations in diagnosis and management. Figures include population prevalence of dizziness symptoms, the anatomy of inner structures, primary afferent vestibular nerve activity, the head thrust test, the Dix-Hallpike maneuver, the supine positional test, the canalith repositioning procedure, and the barbecue roll maneuver. Tables list physiologic properties and clinical features of the components of the peripheral vestibular system, information to be acquired from history of the present illness, common symptoms patients report as dizziness, examination components, distinguishing among common peripheral and central vertigo syndromes, common causes of nonspecific dizziness, types of dizziness presentations, relevant imaging abnormalities on neuroimaging studies, vestibular testing components, and medical therapy for symptomatic dizziness. This review contains 8 highly rendered figures, 11 tables, and 69 references.

Oxford Cases in Medicine and Surgery, second edition, teaches students a logical step-by-step diagnostic approach to common patient presentations. This approach mirrors that used by successful clinicians on the wards, challenging students with questions at each stage of a case (history-taking, examination, investigation, management). In tackling these questions, students understand how to critically analyse information and learn to integrate their existing knowledge to a real-life scenario from start to finish. Each chapter focuses on a common presenting symptom (e.g. chest pain). By starting with a symptom, mirroring real life settings, students learn to draw on their knowledge of different physiological systems - for example, cardiology, respiratory, gastroenterology - at the same time. All the major presenting symptoms in general medicine and surgery are covered, together with a broad range of pathologies. This book is an essential resource for all medicine students, and provides a modern, well-rounded introduction to life on the wards. Ideal for those starting out in clinical medicine and an ideal refresher for those revising for OSCEs and finals.

AbstractThe framework for cadaver surgical training (CST) in Japan was established in 2012, based on the “Guidelines for Cadaver Dissection in Education and Research of Clinical Medicine” of the Japan Surgical Society (JSS) and the Japanese Association of Anatomists. Subsequently, the Ministry of Health, Labor and Welfare allocated funding from its budget for CST. By 2019, CST was being practiced in 33 medical schools and universities. Currently, the CST Promotion Committee of the JSS reviews each CST report submitted by medical schools and universities and provides guidance based on professional autonomy. This paper outlines the history of CST in Japan and presents a plan for its future. To sustain and oversee CST implementation, an operating organization, funded by stakeholders, such as government agencies, academic societies, and private companies, is needed.

A simulation tool for gasification based processes is presented for an equation-oriented, steady state modelling environment. The approach aims at an adequate description of phenomena linked to gasification. Background information is provided regarding the structure of the framework, thermodynamic data processing, and on the formulation of the model equations. The implemented substance streams are water/steam, ideal gases, inorganic solids, and organic mixtures. The models are based upon mass and energy balances and feature thermodynamic considerations. The addition of correlations for fluid dynamics or chemical kinetics is generally possible but not within the focus of this paper. The key-aspects of the typical unit-models, like pumps, turbines, heat exchangers, separators and chemical reactors are highlighted. The model of a dual-fluidized bed biomass gasifier is presented in detail. In a final case study, the suitability of the simulation tool is demonstrated for the description of the gasification-based biomass combined heat and power plant in Güssing/Austria.

This study is devoted to the study of relevant works on the history of the Stavropol Cossacks, works in the field of education of the Stavropol Cossacks as an independent Cossack group, trade, cultural and economic ties in the Stavropol Territory, spiritual life, language, culture, traditions and customs of the Stavropol Cossacks. Among modern studies in the history of the Stavropol Cossacks, the following topics stand out: military life and everyday life, folklore and song traditions, the movement for the revival of the Cossacks, as well as the current state and prospects for the development of Cossack organizations. The prospect of the development of pedagogical technologies based on the Cossack traditions of educating young people in Stavropol is highlighted as a separate topical topic. The relevance of the study lies in the need for a private study of the historiography of the regional Cossack group of Stavropol Cossacks in order to expand the scientific and pedagogical tools in the field of «Cossack studies». The practical significance of the study is expressed in the possibility of using the data of the article in the search for supporting material for teaching the "History of the Cossacks" in a higher educational institution (taking into account the regional specifics). The scientific novelty of the research is expressed in a new view of the Stavropol Cossacks as an independent Cossack group formed at the end of the XVIII century. The source base is represented mainly by archival data from the State Archives of the Stavropol Territory, data banks on archaeological, cultural and linguistic expeditions, sources of personal origin, the works of contemporary historians and directly the works of historians, whose studies formed the basis of the historiography of the history of the Stavropol Cossacks. The research methodology is based on the principles of historiographic comparative studies and comparative analysis of sources. Within the framework of the sociocultural approach, we rely on the following methods. Special-historical: the narrative method, the historical-comparative method, the historical-systemic method, the retrospective method. Sociological: document analysis, method of generalizing characteristics, method of ideal types. Culturological: comparative method, cultural-systemic method. Pedagogical: pedagogical interviewing, a method of studying and generalizing pedagogical experience.

Foreign body aspiration is common in children and in the elderly, who may present with subtle symptoms. Clinical suspicion is crucial and bronchoscopy is the main diagnostic and therapeutic procedure available. This is the case of a man, 78 years old, with a history of chronic obstructive pulmonary disease, who presented with respiratory distress following oral intake of tablets. History taking and physical examination raised suspicion. The diagnosis was confirmed with flexible bronchoscopy and rigid bronchoscopy was carried out for treatment. The patient’s condition is stable and he is under investigations for dysphagia.

Periodic Changes

Since World War II, periodic changes in the fabrication, design, and material specifications for ship steels have been made to preclude brittle fractures. These various changes are described briefly, along with a history of fracture control for ships to serve as background information for a discussion of the present-day structural integrity program for ships in the marine industry. As additional information related to the structural integrity of ship structures, a review of two recent ship failures (e.g., the Ingram Barge in 1972 and the Chester A. Poling in 1977) is presented to demonstrate some of the factors involved in brittle fractures of ships. In both of these failures there were other factors contributing to the final brittle fractures that were more important than the notch toughness levels. These factors are reviewed as the basis for an observation regarding the overall structural integrity of merchant ships.
