Surfactant. Surfactants are compounds that lower the surface tension (or interfacial tension) between two liquids or between a liquid and a solid. Surfactants may act as detergents, wetting agents, emulsifiers, foaming agents, and dispersants.

Ganglion Cyst Surgery
Ganglion Cyst Surgery samer kareem 3,909 Visualizzazioni • 2 anni fa

Surgery involves removing the cyst as well as part of the involved joint capsule or tendon sheath, which is considered the root of the ganglion. Even after excision, there is a small chance the ganglion will return. A ganglion cyst at the wrist is removed during a surgical procedure called excision.

Vomiting and Diarrhea in Kids

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.

Wilms tumor, also known as nephroblastoma, is a cancer of the kidneys that typically occurs in children, rarely in adults. It is named after Dr. Max Wilms, the German surgeon (1867–1918) who first described it. Approximately 500 cases are diagnosed in the U.S. annually.

Ehlers-Danlos Syndrome
Ehlers-Danlos Syndrome samer kareem 12,750 Visualizzazioni • 2 anni fa

Ehlers-Danlos syndrome is a group of disorders that affect the connective tissues that support the skin, bones, blood vessels, and many other organs and tissues. Defects in connective tissues cause the signs and symptoms of Ehlers-Danlos syndrome, which vary from mildly loose joints to life-threatening complications. Previously, there were more than 10 recognized types of Ehlers-Danlos syndrome, differentiated by Roman numerals. In 1997, researchers proposed a simpler classification that reduced the number of major types to six and gave them descriptive names: the classical type (formerly types I and II), the hypermobility type (formerly type III), the vascular type (formerly type IV), the kyphoscoliosis type (formerly type VIA), the arthrochalasia type (formerly types VIIA and VIIB), and the dermatosparaxis type (formerly type VIIC). This six-type classification, known as the Villefranche nomenclature, is still commonly used. The types are distinguished by their signs and symptoms, their underlying genetic causes, and their patterns of inheritance. Since 1997, several additional forms of the condition have been described. These additional forms appear to be rare, affecting a small number of families, and most have not been well characterized.

Bone Tumor. Reasons
Bone Tumor. Reasons samer kareem 5,792 Visualizzazioni • 2 anni fa

Bone tumors develop when cells in the bone divide without control, forming a mass of tissue. Most bone tumors are benign, which means they are not cancer and cannot spread. However, they may still weaken bone and lead to fractures or cause other problems. Bone cancer destroys normal bone tissue and may spread to other parts of the body (called metastasis). Benign Bone Tumors Benign tumors are more common than malignant tumors of the bones. These are a few common types of benign bone tumors: Osteochondroma is the most common benign bone tumor. It is more common in people under age 20. Giant cell tumor is a benign tumor, typically affecting the leg (malignant types of this tumor are uncommon). Osteoid osteoma is a bone tumor, often occurring in long bones, that occurs commonly in the early 20s. Osteoblastoma is a single tumor that occurs in the spine and long bones, mostly in young adults. Enchondroma usually appears in bones of the hand and feet. It often has no symptoms. It is the most common type of hand tumor.

Central Line - Subclavian infraclavicular approach
Central Line - Subclavian infraclavicular approach samer kareem 12,680 Visualizzazioni • 2 anni fa

First described by Aubaniac in 1952, central venous catheterization, or central line placement, is a time-honored and tested technique of quickly accessing the major venous system. Benefits over peripheral access include greater longevity without infection, line security in situ, avoidance of phlebitis, larger lumens, multiple lumens for rapid administration of combinations of drugs, a route for nutritional support, fluid administration, and central venous pressure (CVP) monitoring. Central vein catheterization is also referred to as central line placement. Overall complication rates are as high as 15%, [1, 2, 3, 4] with mechanical complications reported in 5-19% of patients, [5, 6, 7] infectious complications in 5-26%, [1, 2, 4] and thrombotic complications in 2-26%. [1, 8] These complications are all potentially life-threatening and invariably consume significant resources to treat. Placement of a central vein catheter is a common procedure, and house staff require substantial training and supervision to become facile with this technique. A physician should have a thorough foreknowledge of the procedure and its complications before placing a central vein catheter. The supraclavicular approach was first put into clinical practice in 1965 and is an underused method for gaining central access. It offers several advantages over the infraclavicular approach to the subclavian vein. At the insertion site, the subclavian vein is closer to the skin, and the right-side approach offers a straighter path into the subclavian vein. In addition, this site is often more accessible during cardiopulmonary resuscitation (CPR) and during active surgical cases. Finally, in patients who are obese, this anatomic area is less distorted.

Cushing's Disease
Cushing's Disease samer kareem 5,953 Visualizzazioni • 2 anni fa

Cushing's disease is a serious condition of an excess of the steroid hormone cortisol in the blood level caused by a pituitary tumor secreting adrenocorticotropic hormone (ACTH). ACTH is a hormone produced by the normal pituitary gland. ACTH stimulates the adrenal glands (located on top of the kidneys) to produce cortisol, commonly referred to as the stress hormone.

Nelson's syndrome
Nelson's syndrome samer kareem 4,817 Visualizzazioni • 2 anni fa

Nelson syndrome refers to a spectrum of symptoms and signs arising from an adrenocorticotropin (ACTH)–secreting pituitary macroadenoma after a therapeutic bilateral adrenalectomy. The spectrum of clinical features observed relates to the local effects of the tumor on surrounding structures, the secondary loss of other pituitary hormones, and the effects of the high serum concentrations of ACTH on the skin. [1] The first case was reported by Nelson et al in 1958. [2]

Scoliosis
Scoliosis samer kareem 18,795 Visualizzazioni • 2 anni fa

If you look at someone’s back, you’ll see that the spine runs straight down the middle. When a person has scoliosis, their backbone curves to the side. The angle of the curve may be small, large or somewhere in between. But anything that measures more than 10 degrees is considered scoliosis. Doctors may use the letters “C” and “S” to describe the curve of the backbone. You probably don’t look directly at too many spines, but what you might notice about someone with scoliosis is the way they stand. They may lean a little or have shoulders or hips that look uneven. What Causes Scoliosis? In as many as 80% of cases, doctors don’t find the exact reason for a curved spine. Scoliosis without a known cause is what doctors call “idiopathic.” Some kinds of scoliosis do have clear causes. Doctors divide those curves into two types -- structural and nonstructural. In nonstructural scoliosis, the spine works normally, but looks curved. Why does this happen? There are a number of reasons, such as one leg’s being longer than the other, muscle spasms, and inflammations like appendicitis. When these problems are treated, this type of scoliosis often goes away.

Familial Hypocalciuric Hypercalcemia
Familial Hypocalciuric Hypercalcemia samer kareem 4,327 Visualizzazioni • 2 anni fa

There are 3 genetic types of FHH based on chromosome location. FHH type 1 accounts for 65% of cases and is due to inactivating mutations in the CASR gene, localized to 3q21.1. This gene encodes the calcium-sensing receptor (CaSR). Loss of CaSR function results in a reduction in the sensitivity of parathyroid and renal cells to calcium levels so hypercalcemia is perceived as normal. The other 35% have either a mutation GNA11 (19p13.3) seen in FHH type 2 or AP2S1 (19q13.2-q13.3) seen in FHH type 3 (see these terms) or in genes not yet discovered. FHH is rarely caused by auto-antibodies against CaSR in those without a mutation.

Pictures Of Shingles, Images Of Shingles, Cause Of Shingles, Can You Catch Shingles, Cause Shingles --- http://shingles-cure.good-info.co/ ---- Home Remedy For Shingles Treatment. There are surprisingly diverse amounts of treatments that can be used for viruses, especially one in particular known as Shingles. Shingles is the type of virus that is annoyingly unpredictable. Some people get it while others do not, and while it predominant after a certain age, most people can go their whole lives without ever seeing a hint of it. Yet, we all have it living inside of us. The first step to treating the virus correctly is to understand what can set it off. The first pre-requisite is to have had chicken-pox before. Most things manage to squeeze through an immune system if it is weak enough and the shingles virus is no different. In some cases that can kill someone with a weak enough system The shingles virus can also ‘wake up’ if sufficient levels of stress agitate a person’s immune system. As mentioned before, the virus is unpredictable, and even if you meet all the requirements you could go through your entire life without one outbreak. The second step to treating the virus is catching it in time. 72 hours after you first begin to notice symptoms of shingles is pushing your luck so within that time frame some type of treatment should be instigated. For the most part, for a disease like shingles, the main source of relief comes from skin creams and pain killers. Neither of which is a cure for the pain, but which do happen to fall under the heading of ‘home remedy’ Wet rags can be used to soothe the inflamed and tender skin, and a binding with a substance known as aluminum acetate can protect the infected area without causing further irritation. Calamine lotion is a fail safe for almost any sort of skin irritation so it would be smart to go through the aisles at your local grocery store to find products similar. Then of course there are the most obvious measures that need to be taken during your do it yourself treatment sessions. Stay out of the sun since the heat and UV rays can cause unbearable pain against already brutalized skin. Also, keep yourself from scratching at the area since, like the chicken-pox, you will only end up making it worse. If you do not believe me then consider the unlucky individuals who do not have the rash on a small area, but rather all over their bodies. Anti-itch cream would probably be more than appreciated at that point. Should the time come where the virus is making repeated appearances, then it may be time to throw in the towel and head for the hospital. The reason is that after the first outbreak, it isn’t unusual that the virus that was originally stored in the roots of your nerves ‘burned’ itself out. However, continual outbreaks are indications of something deeper that can only grow worse as the attacks continue. Some victims of the virus have described the sensation as having your flesh eaten from the inside out. Once the pain reaches that level, stubbornness should be put on the backburner. If you are forced to go to your local doctor, you may be provided with some of the medicines that have recently been created to help fight off shingles. They are by no means brand names, but neither are they over the counter drugs either. After a few more years to study their effectiveness, there is no reason why this new medication cannot ease the pain caused by shingles, and even, eventually cure it. In this presentation, shows you some unique and rare methods to get rid of shingles naturally in as little as 14 days! This is based on proven techniques used by shingles sufferers without the use of pills and other medication. Get Rid of Shingles will also boost your energy and health dramatically and improve the quality of your life.

A silent heart attack is a heart attack that has few, if any, symptoms. You may have never had any symptoms to warn you that you've developed a heart problem, such as chest pain or shortness of breath. Having diabetes or prediabetes puts you at increased risk for heart disease and stroke. You can lower your risk by keeping your blood glucose (also called blood sugar), blood pressure, and blood cholesterol close to the recommended target numbersthe levels suggested by diabetes experts for good health.

Visualization of the larynx by direct or indirect means is referred to as laryngoscopy and is the principal aim during airway management for passage of a tracheal tube. This paper presents a brief background regarding the development and practice of laryngoscopy and examines the equipment and techniques for both direct and indirect methods. Patient evaluation during the airway examination is discussed, as are predictors for difficult intubation. Laryngoscope blade design, newer intubating techniques, and a variety of indirect laryngoscopic technologies are reviewed, as is the learning curve for these techniques and devices.
