How Ultrasound works
How Ultrasound works samer kareem 2,517 Views • 2 years ago

Ultrasound or ultrasonography is a medical imaging technique that uses high frequency sound waves and their echoes. The technique is similar to the echolocation used by bats, whales and dolphins, as well as SONAR used by submarines. In ultrasound, the following events happen: The ultrasound machine transmits high-frequency (1 to 5 megahertz) sound pulses into your body using a probe. The sound waves travel into your body and hit a boundary between tissues (e.g. between fluid and soft tissue, soft tissue and bone). Some of the sound waves get reflected back to the probe, while some travel on further until they reach another boundary and get reflected. The reflected waves are picked up by the probe and relayed to the machine. The machine calculates the distance from the probe to the tissue or organ (boundaries) using the speed of sound in tissue (5,005 ft/s or1,540 m/s) and the time of the each echo's return (usually on the order of millionths of a second). The machine displays the distances and intensities of the echoes on the screen, forming a two dimensional image like the one shown below.

Depending on the fracture, the bone fragments may be fixed using screws, a plate and screws, or different wiring techniques. Because there is such a wide range of injuries, there is also a wide range of people's specific recovery time for ankle fracture surgery. It takes at least 6 weeks for the broken bones to heal.

Esophageal Atresia
Esophageal Atresia samer kareem 4,696 Views • 2 years ago

Esophageal atresia is an abnormality, or birth defect, of the esophagus that occurs early in pregnancy, as the baby is developing. The esophagus forms in the first few months of fetal life as a long, hollow, continuous tube joining the mouth to the stomach. In newborns with this birth defect, formation of this continuous esophageal tube is interrupted. esophageal-artresia-2In most cases, two separate tubes are formed, an upper (proximal) tube connected to the mouth and a lower (distal) tube connected to the stomach. This seperated tubes are sealed off creating a pouch on either side; the gap between these pounches can be short or very long. Saliva can accumulate in the upper pouch as it cannot drain into the stomach.

Urinary bladder
Urinary bladder samer kareem 9,951 Views • 2 years ago

The urinary bladder is a hollow muscular organ that collects urine from the kidneys before disposal by urination. A hollow muscular, and distensible (or elastic) organ, the bladder sits on the pelvic floor. Urine enters the bladder via the ureters and exits via the urethra.

Spleen
Spleen samer kareem 5,348 Views • 2 years ago

The spleen, a spongy, soft organ about as big as a person’s fist, is located in the upper left part of the abdomen, just under the rib cage. The splenic artery brings blood to the spleen from the heart. Blood leaves the spleen through the splenic vein, which drains into a larger vein (the portal vein) that carries the blood to the liver. The spleen has a covering of fibrous tissue (the splenic capsule) that supports its blood vessels and lymphatic vessels. The spleen is made up of two basic types of tissue, each with different functions: White pulp Red pulp The white pulp is part of the infection-fighting (immune) system. It produces white blood cells called lymphocytes, which in turn produce antibodies (specialized proteins that protect against invasion by foreign substances). The red pulp filters the blood, removing unwanted material. The red pulp contains other white blood cells called phagocytes that ingest microorganisms, such as bacteria, fungi, and viruses. It also monitors red blood cells, destroying those that are abnormal or too old or damaged to function properly. In addition, the red pulp serves as a reservoir for different elements of the blood, especially white blood cells and platelets (cell-like particles involved in clotting). However, releasing these elements is a minor function of the red pulp.

Management of COPD
Management of COPD samer kareem 1,988 Views • 2 years ago

The goal of COPD management is to improve a patient’s functional status and quality of life by preserving optimal lung function, improving symptoms, and preventing the recurrence of exacerbations. Currently, no treatments aside from lung transplantation have been shown to significantly improve lung function or decrease mortality; however, oxygen therapy (when appropriate) and smoking cessation may reduce mortality. Once the diagnosis of COPD is established, it is important to educate the patient about the disease and to encourage his or her active participation in therapy.

This system treats type 2 diabetes by promoting weight loss. samer kareem 14,239 Views • 2 years ago

Diabetes is a growing global health concern, as is obesity. Diabetes and obesity are intrinsically linked: obesity increases the risk of diabetes and also contributes to disease progression and cardiovascular disease. Although the benefits of weight loss in the prevention of diabetes and as a critical component of managing the condition are well established, weight reduction remains challenging for individuals with type 2 diabetes due to a host of metabolic and psychological factors. For many patients, lifestyle intervention is not enough to achieve weight loss, and alternative options, such as pharmacotherapy, need to be considered. However, many traditional glucose-lowering medications may lead to weight gain. This article focuses on the potential of currently available pharmacological strategies and on emerging approaches in development to support the glycemic and weight-loss goals of individuals with type 2 diabetes. Two pharmacotherapy types are considered: those developed primarily for blood glucose control that have a favorable effect on body weight and those developed primarily to induce weight loss that have a favorable effect on blood glucose control. Finally, the potential of combination therapies for the management of obese patients with type 2 diabetes is discussed.

What is a blood clot?
What is a blood clot? samer kareem 3,742 Views • 2 years ago

Blood clotting, or coagulation, is an important process that prevents excessive bleeding when a blood vessel is injured. Platelets (a type of blood cell) and proteins in your plasma (the liquid part of blood) work together to stop the bleeding by forming a clot over the injury.

Vomiting and Diarrhea in Kids
Vomiting and Diarrhea in Kids samer kareem 4,994 Views • 2 years ago

Diarrhea in Children: Common Causes and Treatments Diarrhea is the body's way of ridding itself of germs, and most episodes last a few days to a week. Diarrhea often occurs with fever, nausea, vomiting, cramps, and dehydration. Some of the most common reasons kids get diarrhea include: Infection from viruses like rotavirus, bacteria like salmonella and, rarely, parasites like giardia. Viruses are the most common cause of a child's diarrhea. Along with loose or watery stools, symptoms of a viral gastroenteritis infection often include vomiting, stomachache, headache, and fever. When treating viral gastroenteritis -- which can last 5-14 days -- it's important to prevent fluid loss. Offer additional breast milk or an oral rehydration solution (ORS) to infants and young children. Water alone doesn't have enough sodium, potassium, and other nutrients to safely rehydrate very young children. Be sure to talk to your doctor about the amount of fluids your child needs, how to make sure he or she gets them, when to give them, and how to watch for dehydration. Older children with diarrhea can drink anything they like to stay hydrated, including ORS and brand-name products (their names usually end in "lyte"). Popsicles can also be a good way to get fluids into a child who's been vomiting and needs to rehydrate slowly.

Chronic obstructive pulmonary disease Email this page to a friend Print Facebook Twitter Google+ Chronic obstructive pulmonary disease (COPD) is a common lung disease. Having COPD makes it hard to breathe. There are two main forms of COPD: Chronic bronchitis, which involves a long-term cough with mucus Emphysema, which involves damage to the lungs over time Most people with COPD have a combination of both conditions. Causes Smoking is the main cause of COPD. The more a person smokes, the more likely that person will develop COPD. But some people smoke for years and never get COPD. In rare cases, nonsmokers who lack a protein called alpha-1 antitrypsin can develop emphysema. Emphysema Other risk factors for COPD are: Exposure to certain gases or fumes in the workplace Exposure to heavy amounts of secondhand smoke and pollution Frequent use of a cooking fire without proper ventilation Symptoms Symptoms may include any of the following: Cough, with or without mucous Fatigue Many respiratory infections Shortness of breath (dyspnea) that gets worse with mild activity Trouble catching one's breath Wheezing Because the symptoms develop slowly, some people may not know that they have COPD.

Anti Rides Efficace, Comment Faire Un Régime Pour Mincir Vite, Aliment Brûle Graisse, Poids Graisse ---- http://rajeunir-de-10-ans.info-pro.co --- 5 Raisons pour lesquelles le Cardio traditionnel n’est PAS bon pour vous. Voici le problème : si vous cherchez à rentabiliser au maximum le temps que vous passez à vous entrainer, le cardio de longue durée à faible intensité n'est pas la voie à suivre… et pour de nombreuses raisons. Voici le top 5 de ces raisons : 1. Un nombre réduit de calories brûlées : 45 minutes sur un tapis de course peut vous aider à brûler au maximum 300 calories si vous êtes chanceux, l'équivalent de 50 grammes de graisse. En faisant dix heures de tapis de course par semaine vous pourriez perdre un demi-kilo ! 2. Beaucoup trop de temps consacré : je ne sais pas pour vous, mais je n'ai pas des heures et des heures de mon temps à mettre dans l’entraînement chaque semaine. En fait, j'ai seulement le temps de faire quelques heures d'exercice par semaine, et vous savez quoi ? C'est tout ce dont vous avez besoin. En fait, la recherche a montré que plus de 90 minutes par semaine peuvent être nuisibles! Au-delà de cela, le cardio de longue durée et faible intensité est : 3. Ennuyeux à mourir : assis sur un vélo d'exercice à regarder le mur en face de moi pendant 45-60 minutes ? Non merci. Mais peut-être pire encore est le fait que le cardio de longue durée et à faible intensité ne fournit : Pas d’avantages prolongés au niveau métabolique : saviez-vous qu’avec de l'exercice avec plus d'intensité il est possible de continuer à brûler des calories pour un maximum de 48 heures après l'entraînement ? C'est vrai. Mais vous savez ce qui est vrai également ? Le cardio de longue durée et à faible intensité ne fournit pratiquement aucune stimulation prolongée du métabolisme. En fait, avec un cardio lent et à faible intensité, le métabolisme revient à la normale presque immédiatement après la séance d'exercice. Et enfin, la raison qui l'emporte sur toutes les autres : 5. Une perte de graisse minimale : un minimum de calories sont brûlées pendant la session et pratiquement aucunes calories supplémentaires ne sont brûlées après… donc aucune perte de graisse supplémentaire. Et soyons honnêtes, la seule raison pour laquelle quelqu'un fait du cardio c'est pour avoir des "résultats visibles". Donc, si le cardio de longue durée à faible intensité n'est pas la solution idéale, quelle est-elle ? ET bien les solutions sont multiples et vous n'avez pas besoin de passer des heures et des heures chaque semaine à vous entrainer de façon stupide pour obtenir les meilleures résultats possibles.
