Causes Of Ascites
Causes Of Ascites samer kareem 2,980 Views • 3 years ago

The accumulation of ascitic fluid represents a state of total-body sodium and water excess, but the event that initiates the unbalance is unclear. Although many pathogenic processes have been implicated in the development of abdominal ascites, about 75% likely occur as a result of portal hypertension in the setting of liver cirrhosis, with the remainder due to infective, inflammatory, and infiltrative conditions. Three theories of ascites formation have been proposed: underfilling, overflow, and peripheral arterial vasodilation. The underfilling theory suggests that the primary abnormality is inappropriate sequestration of fluid within the splanchnic vascular bed due to portal hypertension and a consequent decrease in effective circulating blood volume. This activates the plasma renin, aldosterone, and sympathetic nervous system, resulting in renal sodium and water retention. The overflow theory suggests that the primary abnormality is inappropriate renal retention of sodium and water in the absence of volume depletion. This theory was developed in accordance with the observation that patients with cirrhosis have intravascular hypervolemia rather than hypovolemia. The most recent theory, the peripheral arterial vasodilation hypothesis, includes components of both of the other theories. It suggests that portal hypertension leads to vasodilation, which causes decreased effective arterial blood volume. As the natural history of the disease progresses, neurohumoral excitation increases, more renal sodium is retained, and plasma volume expands. This leads to overflow of fluid into the peritoneal cavity. The vasodilation theory proposes that underfilling is operative early and overflow is operative late in the natural history of cirrhosis. Although the sequence of events that occurs between the development of portal hypertension and renal sodium retention is not entirely clear, portal hypertension apparently leads to an increase in nitric oxide levels. Nitric oxide mediates splanchnic and peripheral vasodilation. Hepatic artery nitric oxide synthase activity is greater in patients with ascites than in those without ascites. Regardless of the initiating event, a number of factors contribute to the accumulation of fluid in the abdominal cavity. Elevated levels of epinephrine and norepinephrine are well-documented factors. Hypoalbuminemia and reduced plasma oncotic pressure favor the extravasation of fluid from the plasma to the peritoneal fluid, and, thus, ascites is infrequent in patients with cirrhosis unless both portal hypertension and hypoalbuminemia are present.

Ankle fusion (arthrodesis) This is a surgical procedure which joins together the main bones of the ankle joint (the tibia and the talus).

Perdre Du Ventre, Comment Maigrir Des Cuisses, Regime Soupe, Prendre Du Muscle, Maigrir Des Hanches ---- http://perte-poids-rapide.info-pro.co --- Comment maigrir pour un homme ? Les régimes ne sont pas une exclusivité féminine et les hommes ont eux aussi des comptes à rendre à leur balance. Pour séduire, pour se sentir mieux dans leur corps, pour leur travail, ils ont eux aussi des raisons pour se délester de quelques kilos. Hommes et femmes : différentes face aux kilos Les hommes et les femmes ne réagissent pas de la même manière face au poids. Le corps non plus. La première différence est au niveau de la silhouette. La gente féminine va accumuler les kilos en trop au niveau des fesses et des cuisses alors que pour les hommes, la prise de poids se situe surtout au niveau du visage, du cou et du ventre. L’autre différence entre les hommes et les femmes est la faculté à perdre du poids. Si vous avez décidé de suivre un régime en couple, sachez Mesdames que les hommes maigrissent plus vite ! Cette « injustice » est expliquée par le fait que les hommes ou plutôt leur organisme, va brûler plus de calories au repos et à l’effort que les femmes grâce à leur masse corporelle plus importante. Par contre, ces dames sont plus motivées à tenir un régime sur la longueur. Les hommes et les régimes, c’est toute une histoire ! C’est pourquoi ils doivent faire un régime qui leur corresponde et qui est adapté à leur vie au quotidien ! Maigrir lorsque l’on est un homme Les hommes sont de plus en plus nombreux à vouloir perdre du poids. Surtout entre 40 et 45 ans. Mais même s’ils maigrissent plus vite que les femmes, la partie est loin d’être gagnée. Pourquoi ? Parce qu’il est plus compliqué pour eux de modifier leurs habitudes alimentaires. En effet, ce sont les vrais champions d’une alimentation riche en matières grasses, peu variée et très déséquilibrée. Il faut donc qu’ils adoptent de nouvelles habitudes alimentaires tout en conservant une certaines notion de plaisir et qu’ils combattent certaines mauvaises habitudes, souvent responsable de leurs kilos en trop.

Rabies
Rabies samer kareem 7,275 Views • 3 years ago

In developing countries, domestic animals (eg, dogs) are common sources of infection. In the United States, bats and wild animals (eg, raccoons) are the most common reservoirs of infection. The acquisition of rabies from bats can occur from an unrecognized bite or a scratch, and possibly by inhalation of aerosolized viral particles. Bats are found in all states except Hawaii, and spelunking (cave exploration) is a risk factor for rabies acquisition from bats.

In nonsurgical treatment, progressive physical therapy and rehabilitation can restore the knee to a condition close to its pre-injury state and educate the patient on how to prevent instability.37, 38 This may be supplemented with the use of a hinged knee brace. However, many people who choose not to have surgery may experience secondary injury to the knee due to repetitive instability episodes. Surgical treatment is usually advised in dealing with combined injuries (ACL tears in combination with other injuries in the knee). However, deciding against surgery is reasonable for select patients. Nonsurgical management of isolated ACL tears is likely to be successful or may be indicated in patients:

How Fibroids Are Treated
How Fibroids Are Treated samer kareem 8,968 Views • 3 years ago

There's no single best approach to uterine fibroid treatment — many treatment options exist. If you have symptoms, talk with your doctor about options for symptom relief. Watchful waiting Many women with uterine fibroids experience no signs or symptoms, or only mildly annoying signs and symptoms that they can live with. If that's the case for you, watchful waiting could be the best option. Fibroids aren't cancerous. They rarely interfere with pregnancy. They usually grow slowly — or not at all — and tend to shrink after menopause, when levels of reproductive hormones drop. Medications Medications for uterine fibroids target hormones that regulate your menstrual cycle, treating symptoms such as heavy menstrual bleeding and pelvic pressure. They don't eliminate fibroids, but may shrink them. Medications include: Gonadotropin-releasing hormone (Gn-RH) agonists. Medications called Gn-RH agonists (Lupron, Synarel, others) treat fibroids by blocking the production of estrogen and progesterone, putting you into a temporary postmenopausal state. As a result, menstruation stops, fibroids shrink and anemia often improves. Your doctor may prescribe a Gn-RH agonist to shrink the size of your fibroids before a planned surgery. Many women have significant hot flashes while using Gn-RH agonists. Gn-RH agonists typically are used for no more than three to six months because symptoms return when the medication is stopped and long-term use can cause loss of bone. Progestin-releasing intrauterine device (IUD). A progestin-releasing IUD can relieve heavy bleeding caused by fibroids. A progestin-releasing IUD provides symptom relief only and doesn't shrink fibroids or make them disappear. It also prevents pregnancy. Tranexamic acid (Lysteda). This nonhormonal medication is taken to ease heavy menstrual periods. It's taken only on heavy bleeding days. Other medications. Your doctor might recommend other medications. For example, oral contraceptives or progestins can help control menstrual bleeding, but they don't reduce fibroid size. Nonsteroidal anti-inflammatory drugs (NSAIDs), which are not hormonal medications, may be effective in relieving pain related to fibroids, but they don't reduce bleeding caused by fibroids. Your doctor may also suggest that you take vitamins and iron if you have heavy menstrual bleeding and anemia
