Western Blot HIV Test
Western Blot HIV Test samer kareem 5,079 Views • 2 years ago

The window period is the time from infection until a test can detect any change. The average window period with HIV-1 antibody tests is 25 days for subtype B. Antigen testing cuts the window period to approximately 16 days and nucleic acid testing (NAT) further reduces this period to 12 days.[2] Performance of medical tests is often described in terms of: sensitivity: The percentage of the results that will be positive when HIV is present specificity: The percentage of the results that will be negative when HIV is not present. All diagnostic tests have limitations, and sometimes their use may produce erroneous or questionable results. False positive: The test incorrectly indicates that HIV is present in a non-infected person. False negative: The test incorrectly indicates that HIV is absent in an infected person.

Psychological Erectile Dysfunction
Psychological Erectile Dysfunction samer kareem 1,682 Views • 2 years ago

Erectile dysfunction (ED) is the inability to get or keep an erection firm enough for sexual function. It’s a common sexual problem, affecting as many as 30 million men in the United States. Most cases of ED have a physical cause, such as heart disease, diabetes, and obesity. Lifestyle choices like smoking and drinking excessive amounts of alcohol can also lead to ED. But for some men, psychological issues are the root of the problem.

Subphrenic abscess CXR
Subphrenic abscess CXR samer kareem 1,587 Views • 2 years ago

Suspect that a patient has a subphrenic abscess if he deteriorates, or recovers and then deteriorates, between the 14th and the 21st day after a laparotomy, with a low, slowly increasing, swinging fever, sweating, and a tachycardia. This, and a leucocytosis, show that he has ''pus somewhere', which is making him anorexic, wasted, and ultimately cachectic. If he has no sign of a wound infection, a rectal examination is negative, and his abdomen is soft and relaxed, the pus is probably under his diaphragm. The pus might be between his diaphragm and his liver, in (1) his right or (2) his left subphrenic space, or under his liver in (3) his right or (4) his left subhepatic space in his lesser sac. He may have pus in more than one of these spaces. Explore him on the suspicion that he might have a subphrenic abscess. Exploration is not a major operation; the difficulty is knowing where to explore, so refer him if you can. If you cannot refer him, explore him yourself. If you fail to find pus, you have done him no harm; missing a subphrenic abscess is far worse. If it is anterior, you can drain it by going under his costal margin anteriorly. If it is posterior, you can go through the bed of his 12th rib posteriorly.

Kidney Transplant & Dialysis
Kidney Transplant & Dialysis samer kareem 6,938 Views • 2 years ago

Dialysis and kidney transplantation are treatments for severe kidney failure, also called kidney (or renal) failure, stage 5 chronic kidney disease, and end-stage kidney (or renal) disease. There are two types of dialysis: hemodialysis and peritoneal dialysis. When the kidneys are no longer working effectively, waste products, electrolytes, and fluid build up in the blood. Dialysis takes over a portion of the function of the failing kidneys to remove the fluid and waste products. Kidney transplantation can more completely take over the function of the failing kidneys.

Your kidneys are two bean-shaped organs that lie just below your rib cage, on each side of your spine. They remove waste from your body, level out your blood pressure, and keep your bones strong. They also ensure that you have the right amount of chemicals, like potassium and sodium (salt), in your blood. Finally, they make the hormone that causes your body to create red blood cells.

Niemann-Pick Disease
Niemann-Pick Disease samer kareem 1,577 Views • 2 years ago

Niemann-Pick disease is a condition that affects many body systems. It has a wide range of symptoms that vary in severity. Niemann-Pick disease is divided into four main types: type A, type B, type C1, and type C2. These types are classified on the basis of genetic cause and the signs and symptoms of the condition. Infants with Niemann-Pick disease type A usually develop an enlarged liver and spleen (hepatosplenomegaly) by age 3 months and fail to gain weight and grow at the expected rate (failure to thrive). The affected children develop normally until around age 1 year when they experience a progressive loss of mental abilities and movement (psychomotor regression). Children with Niemann-Pick disease type A also develop widespread lung damage (interstitial lung disease) that can cause recurrent lung infections and eventually lead to respiratory failure. All affected children have an eye abnormality called a cherry-red spot, which can be identified with an eye examination. Children with Niemann-Pick disease type A generally do not survive past early childhood.
