BACKGROUND: The Virtual Interprofessional Patients-Computer-Assisted Reproductive Health Education for Students (VIP-CARES) Project took place during the summers of 2010-2012 for eight weeks each year at the University of British Columbia (UBC). Undergraduate health care students worked collaboratively to develop virtual patient case-based learning modules on the topic of family planning. The purpose of this study was to evaluate the changes in perception towards interprofessional collaboration (IPC) among the participants, before and after the project...

In the acute care setting, radiologists are frequently asked to assist in the evaluation of patients presenting with signs and symptoms of lower extremity peripheral vascular disease. Non-traumatic peripheral vascular emergencies are most commonly the result of thrombosis, either in a native vessel or within a bypass graft or stent. Arterial emboli, peripheral aneurysm with embolus or thrombosis, and direct arterial trauma are additional, less common causes. Traumatic peripheral vascular emergencies include vessel occlusion, transection, pseudoaneurysms, active extravasation, and arteriovenous fistulas...

James Parkinson, in his "Essay on the Shaking Palsy" from 1817 described for the first time the disease that later on carried his name. Its anatomical substrate remained controversial for over 100 years. The first case that suggested the association between Parkinson's disease and substantia nigra was published in 1893 Blocq and Marinesco, two scientists who worked at Salpêtrière. The article described a 38 years-old man, with tuberculosis, who was admitted to the Charcot's neurological ward because he also showed signs of unilateral Parkinsonism...

Since abortion became legal nationwide, federal and state "conscience clauses" have been established to define the context in which health professionals may decline to participate in contested services. Patients and health care providers may act according to conscience in making health care decisions and in deciding whether to abstain from or to participate in contested services. Historically, however, conscience clauses largely have equated conscience in health care with provider abstinence from such services...

Routine posteroanterior chest radiographs and computed tomography scans are more sensitive for detecting pneumothoraces than anteroposterior chest radiographs. However, supine chest radiographs are commonly performed as part of the initial and routine assessment of trauma and critically ill patients. Rates of occult pneumothorax can be as high as 50% and have a significant impact in the mortality of these patients; thus, a prompt diagnosis of this entity is important. This pictorial essay will illustrate the pleural anatomy, explain the distribution of air within the pleural space in the supine position, and review the radiologic findings that characterize this entity...

According to the biological definition of death, a human body that has not lost the capacity to holistically organize itself is the body of a living human individual. Reasonable doubt against the conclusion that it has lost the capacity exists when the body appears to express it and no evidence to the contrary is sufficient to rule out reasonable doubt against the conclusion that the apparent expression is a true expression (i.e., when the conclusion that what appears to be holistic organization is in fact holistic organization remains a reasonable explanatory hypothesis in light of the best evidence to the contrary)...

BACKGROUND: A standardized imaging proposal evaluating implanted left atrial appendage (LAA) occlusion devices by cardiac computed tomography angiography (cCTA) has never been investigated. METHODS: cCTA datasets were acquired on a 3(rd) generation dual-source CT system and reconstructed with a slice thickness of 0.5 mm. An interdisciplinary evaluation was performed by two interventional cardiologists and one radiologist on a 3D multi-planar workstation. A standardized multi-planar reconstruction algorithm was developed in order to assess relevant clinical aspects of implanted LAA occlusion devices being outlined within a pictorial essay...

This essay reviews four recent studies representing a new direction in the history of pharmaceuticals and pharmaceutical science. To this end, it introduces the notion of a symbolic economy of drugs, defined as the production, circulation, and reception of signs that convey information about drugs and establish trust in them. Each of the studies under review focuses on one key signifier in this symbolic economy, namely the brand, the patent, the clinical trial, and the drug itself. Drawing on Pierre Bourdieu's theory of the economy of symbolic goods, I conceptualize these signifiers as symbolic assets, that is, as instruments of communication and credit, delivering knowledge, carrying value, and producing authority...

Hyperechoic lesions are not a frequent finding at breasts ultrasonography, and most of times are associated with benign pathologies that do not require further evaluation. However, some neoplasms such as invasive breast carcinomas and metastases may present with hyperechogenicity. Thus, the knowledge about differential diagnoses and identification of signs of lesion aggressiveness are of great relevance to avoid unnecessary procedures or underdiagnosis, and to support the correct clinical/surgical approach...

INTRODUCTION: To perform a meta-analysis to review the sensitivity and specificity of computed tomography and different known computed yomography signs for the diagnosis of strangulation in patients with acute small bowel obstruction. METHODS: A comprehensive Pubmed search was performed for all reports that evaluated the use of CT and discussed different CT criteria for the diagnosis of acute SBO. Articles published in English language from January 1978 to June 2008 were included...

In the first century B.C.E., a group of Greek physicians called the Methodists denied that medicine could be based on such "hidden causes" as humors, atoms, or elements. They argued that the inner workings of the body were ultimately unknowable, existing beyond the limits of human knowledge and inference. Yet they insisted that medical certainty was still possible, claiming that every disease shared one of three directly apprehensible "manifest commonalities"--stricture, laxity, or some mixture of the two. Medicine could therefore be a science; it was simply noncausal in structure...

Despite the fact that ophthalmology is one of the foremost branches of medicine, conceptualization of the structure and function of the eye barely advanced in ancient Western civilizations. At the early recovery of Persian civilization (9(th) century AD) after the extinction of the Sassanid Empire (7(th) century AD), translations of Greek medical textbooks played an important role in the development of medicine and the emergence of great Persian physicians such as Rhazes, Avicenna and others. Rhazes was a leading Persian physician whose medical teachings have as yet not been thoroughly explored...

Background: Digital technologies have transformed nearly every aspect of our lives. However, for many of us, they have not yet improved the way we receive or participate in our health services and disease care. Hostetter et al. (2014) explore in a new multimedia essay the changes occurring with the arrival of new digital tools, from mobile apps and data-driven software solutions to wearable sensors that transmit information to a patient's team of health care providers. Digitisation will revolutionise health technology to a new extent, as the self-measurement, cloud services, teleconsultation and robotics technologies are being used to get health expenditure under control...

The erythrocytes of mammals represent a good model to evaluate the cytotoxicity of molecules, organic and inorganic, natural or synthetic, by cellular damage measure. Indeed, before any investigation on the mechanism of action of different molecules, it is important to perform a cytotoxicity assay. Among the different cytotoxicity assays that assess a possible toxicity in the red blood cells is the rate of haemolysis. This essay is based on the evaluation of the alterations of red cell membranes in the presence of an eventual xenobiotic...

This essay examines how marriage relationships came to be constituted as therapeutic objects after WWII and the impact that this had on British postwar understandings of the meaning of marriage. In contrast to prevailing concerns during the interwar decades about sexual dissatisfaction as the chief impediment to marital stability, post-WWII marriage counselors and therapists framed marital harmony as dependent upon spouses' psychological maturity. An inability to sustain a stable marriage was interpreted as a sign of arrested development, most often stemming from a dysfunctional relationship with one or both parents in childhood...

There are a few signs in radiology which are based on many common objects or patterns that we come across in our routine lives. The objective behind the association between such common objects and the corresponding pathologies is to make the reader understand and remember the disease process. These signs do not necessarily indicate a particular disease, but are usually suggestive of a group of similar pathologies which will facilitate in the narrowing down of the differential diagnosis. These signs can be seen in different imaging modalities like plain radiograph and computed tomography...

BACKGROUND: More than half of the world's adults carry Helicobacter pylori. The eradication of H. pylori may affect the regulation of human metabolic hormones. The aim of this study was to evaluate the effect of H. pylori eradication on meal-associated changes in appetite-controlled insulinotropic and digestive hormones, and to assess post-eradication changes in body mass index as part of a currently on-going multicentre ESSAY (Eradication Study in Stable Adults/Youths) study. METHODS: We enrolled 29 H...

Modern Western medical individualism has had a significant impact on health care in China. This essay demonstrates the ways in which such Western-style individualism has been explicitly endorsed in China's 2010 directive: The Basic Norms of the Documentation of the Medical Record. The Norms require that the patient himself, rather than a member of his family, sign each informed consent form. This change in clinical practice indicates a shift toward medical individualism in Chinese healthcare legislation. Such individualism, however, is incompatible with the character of Chinese familism that is deeply rooted in the Chinese ethical tradition...

Presented cognitive studies aimed to identifying the individual properties of macro saccades, one of the most important oculomotor functions during text, the fairy tales reading. We measure, in the form of abstracts, the reduced analogue of the "school essays", the capabilities of our subjects, the students of liberal arts colleges, to understand the presented text (morality of tales). Evaluation of this abstracts was conducted by independent experts using school 6 point scales. The preparing of the abstract wasn't limited in time...

A wide variety of pathologic processes, both benign and malignant, affect the central airways. These processes may be classified into 4 distinct groups: anatomic variants, lesions that result in focal or diffuse airway narrowing, and those that result in multinodular airway disorder. Key to the accurate assessment of the central airways is meticulous imaging technique, especially the routine acquisition of contiguous high-resolution, 1-mm to 1.5-mm images. These images enable high-definition axial, coronal, and sagittal reconstructions, as well as advanced imaging techniques, including minimum intensity projection images and virtual bronchoscopy...
