Esophageal strictureA benign esophageal stricture, or peptic stricture, is a narrowing or tightening of the esophagus that causes swallowing difficulties. Symptoms of esophageal strictures include heartburn, bitter or acid taste in the mouth, choking, coughing, shortness of breath, frequent burping or hiccups, pain or trouble swallowing, throwing up blood, or weight loss. It can be caused by or associated with gastroesophageal reflux disease, esophagitis, a dysfunctional lower esophageal sphincter, disordered motility, lye ingestion, or a hiatal hernia.
Surgical pathologySurgical pathology is the most significant and time-consuming area of practice for most anatomical pathologists. Surgical pathology involves gross and microscopic examination of surgical specimens, as well as biopsies submitted by surgeons and non-surgeons such as general internists, medical subspecialists, dermatologists, and interventional radiologists. The practice of surgical pathology allows for definitive diagnosis of disease (or lack thereof) in any case where tissue is surgically removed from a patient.
ConsiderationConsideration is a concept of English common law and is a necessity for simple contracts but not for special contracts (contracts by deed). The concept has been adopted by other common law jurisdictions. The court in Currie v Misa declared consideration to be a “Right, Interest, Profit, Benefit, or Forbearance, Detriment, Loss, Responsibility”. Thus, consideration is a promise of something of value given by a promissor in exchange for something of value given by a promisee; and typically the thing of value is goods, money, or an act.
Esophageal dysphagiaEsophageal dysphagia is a form of dysphagia where the underlying cause arises from the body of the esophagus, lower esophageal sphincter, or cardia of the stomach, usually due to mechanical causes or motility problems. Patients usually complain of dysphagia (the feeling of food getting stuck several seconds after swallowing), and will point to the suprasternal notch or behind the sternum as the site of obstruction. If there is dysphagia to both solids and liquids, then it is most likely a motility problem.
PhotothérapieLa photothérapie, en médecine, est un moyen de traitement à l'aide d'un rayonnement électromagnétique non ionisant, c'est-à-dire la lumière le plus souvent. On distingue la photothérapie simple, utilisée en ophtalmologie (exemple de la rétinopathie diabétique) ou en pédiatrie (exemple de l'ictère), et la photochimiothérapie, où un produit photosensibilisant est administré au patient avant exposition, utilisée en ophtalmologie (exemple de la dégénérescence maculaire liée à l'âge) ou en dermatologie (exemple du psoriasis avec la PUVA-thérapie).
Probabilitévignette|Quatre dés à six faces de quatre couleurs différentes. Les six faces possibles sont visibles. Le terme probabilité possède plusieurs sens : venu historiquement du latin probabilitas, il désigne l'opposé du concept de certitude ; il est également une évaluation du caractère probable d'un événement, c'est-à-dire qu'une valeur permet de représenter son degré de certitude ; récemment, la probabilité est devenue une science mathématique et est appelée théorie des probabilités ou plus simplement probabilités ; enfin une doctrine porte également le nom de probabilisme.
Consideration in English lawConsideration is an English common law concept within the law of contract, and is a necessity for simple contracts (but not for special contracts by deed). The concept of consideration has been adopted by other common law jurisdictions, including the US. Consideration can be anything of value (such as any goods, money, services, or promises of any of these), which each party gives as a quid pro quo to support their side of the bargain. Mutual promises constitute consideration for each other.
Empirical probabilityIn probability theory and statistics, the empirical probability, relative frequency, or experimental probability of an event is the ratio of the number of outcomes in which a specified event occurs to the total number of trials, i.e., by means not of a theoretical sample space but of an actual experiment. More generally, empirical probability estimates probabilities from experience and observation. Given an event A in a sample space, the relative frequency of A is the ratio \tfrac m n, m being the number of outcomes in which the event A occurs, and n being the total number of outcomes of the experiment.
Inductive probabilityInductive probability attempts to give the probability of future events based on past events. It is the basis for inductive reasoning, and gives the mathematical basis for learning and the perception of patterns. It is a source of knowledge about the world. There are three sources of knowledge: inference, communication, and deduction. Communication relays information found using other methods. Deduction establishes new facts based on existing facts. Inference establishes new facts from data. Its basis is Bayes' theorem.
Probabilité a prioriDans le théorème de Bayes, la probabilité a priori (ou prior) désigne une probabilité se fondant sur des données ou connaissances antérieures à une observation. Elle s'oppose à la probabilité a posteriori (ou posterior) correspondante qui s'appuie sur les connaissances postérieures à cette observation. Le théorème de Bayes s'énonce de la manière suivante : si . désigne ici la probabilité a priori de , tandis que désigne la probabilité a posteriori, c'est-à-dire la probabilité conditionnelle de sachant .
