Giardiasis Giardiasis (popularly known as beaver fever) is a zoonotic parasitic disease caused by the flagellate protozoan Giardia lamblia (also sometimes called Giardia intestinalis and Giardia duodenalis). The giardia organism inhabits the digestive tract of a wide variety of domestic and wild animal species, as well as humans. It is the most common pathogenic parasitic infection in humans worldwide; in 2013, there were about 280 million people worldwide with symptomatic giardiasis. Signs and symptoms Symptomatic infections are well recognized as causing lactose intolerance, which, while usually temporary, may become permanent. Although hydrogen breath tests indicate poorer rates of carbohydrate absorption in those asymptomatically infected, such tests are not diagnostic of infection. It has been suggested that these observations are explained by symptomatic giardia infection allowing for the overgrowth of other bacteria. Cause Risk factors Research
Heart murmur Murmurs are pathologic heart sounds that are produced as a result of turbulent blood flow across the heart valve that is sufficient to produce audible noise. Most murmurs can only be heard with the assistance of a stethoscope ("or auscultation"). A functional murmur or "physiologic murmur" is a heart murmur that is primarily due to physiologic conditions outside the heart, as opposed to structural defects in the heart itself. Functional murmurs are benign (an "innocent murmur"). Murmurs may also be the result of various problems, such as narrowing or leaking of valves, or the presence of abnormal passages through which blood flows in or near the heart. Heart murmurs are most frequently categorized by timing, into systolic heart murmurs and diastolic heart murmurs. Classification Murmurs can be classified by seven different characteristics: timing, shape, location, radiation, intensity, pitch and quality. Radiation refers to where the sound of the murmur radiates. Systolic
WIKIPEDIA - Colon irritable. Un article de Wikipédia, l'encyclopédie libre. Diagnostic[modifier | modifier le code] Des critères diagnostiques ont été développés (appelés ROME III) et peuvent être classé en deux catégories : douleurs abdominales récidivantes. Ces douleurs abdominales sont généralement exprimées par des crampes intestinales, des ballonnements et/ou des flatulences. Habituellement le rythme des selles est le critère le plus fréquemment utilisé. De nombreux autres symptômes peuvent accompagner les signes digestifs : maux de tête, fatigue, irritabilité, symptômes urinaires ou règles difficiles, dépression… L'examen clinique est sensiblement normal mais se doit de rechercher une cause autre aux douleurs décrites. Aspects historiques[modifier | modifier le code] C'est une maladie qui pourrait s'être développée avec la sédentarisation et les modes de vie modernes. Sa prévalence était néanmoins autrefois mal mesurée. Mécanisme[modifier | modifier le code] Épidémiologie[modifier | modifier le code]
Orthostatic hypotension Orthostatic hypotension, also known as postural hypotension, orthostasis, and colloquially as head rush or dizzy spell, is a form of hypotension in which a person's blood pressure suddenly falls when standing up or stretching. In medical terms, it is defined as a fall in systolic blood pressure of at least 20 mm Hg or diastolic blood pressure of at least 10 mm Hg when a person assumes a standing position. The symptom is caused by blood pooling in the lower extremities upon a change in body position. It is quite common and can occur briefly in anyone, although it is prevalent in particular among the elderly, and those with low blood pressure. Signs and symptoms When orthostatic hypotension is present, the following symptoms can occur after sudden standing or stretching (after standing): They are consequences of insufficient blood pressure and cerebral perfusion (blood supply).

Enteric duplication cyst Enteric duplication cysts, sometimes simply called duplication cysts, are rare congenital malformations of the gastrointestinal tract. They most frequently occur in the small intestine, particularly the ileum, but can occur anywhere along the gastrointestinal tract. They may be cystic or tubular in conformation. The condition of having duplication cysts has been called intestinal duplication. Symptoms Treatment Duplications are usually removed surgically, even if they are found incidentally (i.e. not causing symptoms or encountered on routine studies for other reasons), as there is a high incidence of complications resulting from untreated cases. Cysts are often technically easier to remove than tubular malformations since tubular structures usually share a blood supply with the associated gut.

Palpitation Palpitation is an abnormality of heartbeat that ranges from often unnoticed skipped beats or accelerated heart rate to very noticeable changes accompanied by dizziness or difficulty breathing. Palpitations are common and occur in most individuals with healthy hearts. Palpitations without underlying heart disease are generally considered benign. However, heart palpitations can be a symptom of a serious illness such as coronary heart disease, asthma, or emphysema. Palpitations may be associated with heart problems, but also with kidney disease, electrolyte imbalances for magnesium, potassium and calcium, thyroid malfunction, asthma, and deficiencies or lowered stores of certain nutrients which may include, but are not limited to, taurine, arginine, iron (anemias), potassium and magnesium. Attacks can last for a few seconds or hours, and may occur very infrequently, or more than daily. Causes Palpitations can be attributed to one of four main causes: Anxiety and stress
LE FIGARO SANTE - Syndrome du côlon irritable - Quel régime alimentaire adopter ? Les recommandations alimentaires pour les personnes atteintes du syndrome du côlon irritable visent à diminuer l’hyperstimulation et l’hyperdistension (gonflements importants) des intestins qui provoquent les inconforts. Les fibres Les fibres solubles, comme la pectine, sont contenues dans les fruits et participent aux phénomènes de digestion. Elles sont douces pour l’intestin car elles se transforment en gel lors de la digestion et ainsi n’augmentent pas l’irritation, à la différence des fibres insolubles. Les matières grasses Les matières grasses stimulent fortement les mouvements appelés « réflexes gastro-coliques » de l'intestin. Les aliments qui fermentent Les glucides subissent un processus de fermentation acide qui s’accompagne d’un dégagement de gaz qui vont créer des mouvements de l’intestin. Les aliments irritants Les légumes crus sont plus irritants que les légumes cuits.
Dysautonomia Dysautonomia (or autonomic dysfunction) is any disease or malfunction of the autonomic nervous system (ANS). The autonomic nervous system controls a number of functions in the body, such as heart rate, blood pressure, digestive tract peristalsis, and sweating, amongst others. Dysfunction of the ANS can involve any of these functions. A number of conditions are forms of dysautonomia: postural orthostatic tachycardia syndrome (POTS), inappropriate sinus tachycardia (IST), vasovagal syncope, pure autonomic failure, neurocardiogenic syncope (NCS), neurally mediated hypotension (NMH), orthostatic hypotension, orthostatic hypertension, autonomic instability, paroxysmal sympathetic hyperactivity, and a number of lesser-known disorders such as cerebral salt-wasting syndrome. Signs and symptoms The symptoms of dysautonomia are numerous and vary widely from person to person. The primary symptoms present in patients with dysautonomia are: Causes Management Prognosis
Pancreatitis Pancreatitis is defined as inflammation of the pancreas. It has several causes and symptoms and requires immediate medical attention. It occurs when pancreatic enzymes (especially trypsin) that digest food are activated in the pancreas instead of the small intestine. It may be acute—beginning suddenly and lasting a few days, or chronic—occurring over many years. Signs and symptoms Causes There is an inherited form that results in the activation of trypsinogen within the pancreas, leading to autodigestion. Less common causes include pancreatic cancer, pancreatic duct stones, vasculitis (inflammation of the small blood vessels in the pancreas), coxsackievirus infection, and porphyria—particularly acute intermittent porphyria and erythropoietic protoporphyria. Infectious causes A number of infectious agents have been recognized as causes of pancreatitis including: Diagnosis Acute exudative pancreatitis on CT scan Treatment Mild acute pancreatitis
Myofascial pain syndrome Myofascial pain syndrome (MPS), also known as chronic myofascial pain (CMP), is a syndrome characterized by chronic pain caused by multiple trigger points and fascial constrictions. Characteristic features of a myofascial trigger point include: focal point tenderness, reproduction of pain upon trigger point palpation, hardening of the muscle upon trigger point palpation, pseudo-weakness of the involved muscle, referred pain, and limited range of motion following approximately 5 seconds of sustained trigger point pressure. Symptoms Myofascial pain can occur in distinct, isolated areas of the body, and because any muscle or fascia may be affected, this may cause a variety of localized symptoms. More generally speaking, the muscular pain is steady, aching, and deep. MPS and fibromyalgia MPS and fibromyalgia share some common symptoms, such as hyperirritability, but the two conditions are distinct. Causes The precise causes of MPS are not fully documented or understood.
