Western Blot HIV Test
Western Blot HIV Test samer kareem 5,067 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.

If you have gestational diabetes, your baby may be at increased risk of: Excessive birth weight. Extra glucose in your bloodstream crosses the placenta, which triggers your baby's pancreas to make extra insulin. This can cause your baby to grow too large (macrosomia).

PCP (Phencyclidine)
PCP (Phencyclidine) samer kareem 3,532 Views • 2 years ago

Phencyclidine (PCP) was developed in the 1950s as an intravenous anesthetic but, due to the side effects of confusion and delirium, its development for human medical use was discontinued. In its pure form, it is a white crystalline powder that readily dissolves in water or alcohol and has a distinctive bitter chemical taste. On the illicit drug market, Phencyclidine contains a number of contaminants as a result of makeshift manufacturing, causing the color to range from tan to brown, and the consistency to range from powder to a gummy mass. It is available in a variety of tablets, capsules, and colored powders, which are either taken orally or snorted. The liquid form of phencyclidine is actually phencyclidine base dissolved most often in ether, a highly flammable solvent. For smoking, phencyclidine is typically sprayed onto leafy material such as mint, parsley, oregano, or marijuana.

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.

Kidney Transplant & Dialysis
Kidney Transplant & Dialysis samer kareem 6,926 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.

Super Obese individuals (people with a Body Mass Index over 45) have an increased risk during any surgery. And the longer the time under anesthesia, the greater the risk. Gastric bypass surgery can last over 2 hours. Duodenal switch surgery often takes over 4 hours. That’s a long time to be under anesthesia.

One thing we do know: We can live without it, without apparent consequences. Appendicitis is a medical emergency that requires prompt surgery to remove the appendix. Left untreated, an inflamed appendix will eventually burst, or perforate, spilling infectious materials into the abdominal cavity.

How do dental implants work?
How do dental implants work? samer kareem 1,657 Views • 2 years ago

The dental implant, usually a cylindrical and/or tapered post made of titanium, is placed surgically into the jawbone. As you heal, your implant will osseointegrate, or fuse with, your natural jawbone, with the two growing together to form a strong and long-lasting foundation for your replacement teeth.

Why Can't We Reverse Nerve Damage?
Why Can't We Reverse Nerve Damage? samer kareem 3,375 Views • 2 years ago

Our nervous system is involved in everything our body does, from maintaining our breath to controlling our muscles. Our nerves are vital to all we do; therefore, nerve pain and damage can heavily influence our quality of life. In Discovery News' latest video, "Why Can't We Reverse Nerve Damage?" host Lissette Padilla explains the central nervous system (CNS) has certain proteins that inhibit cell regeneration, because each cell in the nervous system has a unique function on the pathway, like a circuit, and can't be replaced.

Bartter vs Gitelman syndrome
Bartter vs Gitelman syndrome samer kareem 1,776 Views • 2 years ago

Bartter syndrome has traditionally been classified into three main clinical variants, as follows: Neonatal (or antenatal) Bartter syndrome Classic Bartter syndrome Gitelman syndrome Advances in molecular diagnostics have revealed that Bartter syndrome results from mutations in numerous genes that affect the function of ion channels and transporters that normally mediate transepithelial salt reabsorption in the distal nephron segments. Hundreds of mutations have been identified to date. Such advances may result in the development of new therapies (see the image below). [2] (See Pathophysiology and Etiology.)
