Western Blot HIV Test
Western Blot HIV Test samer kareem 5,068 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.

Phenylketonuria
Phenylketonuria samer kareem 4,061 Views • 2 years ago

PKU is inherited in families in an autosomal recessive pattern. Autosomal recessive inheritance means that a person has two copies of the gene that is altered. Usually, each parent of an individual who has PKU carries one copy of the altered gene. ... Gene alterations (mutations) in the PAH gene cause PKU.

Classical PKU is an autosomal recessive disorder, caused by mutations in both alleles of the gene for phenylalanine hydroxylase (PAH), found on chromosome 12. In the body, phenylalanine hydroxylase converts the amino acid phenylalanine to tyrosine, another amino acid.

Subphrenic abscess CXR
Subphrenic abscess CXR samer kareem 1,580 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.

Dumping Syndrome
Dumping Syndrome samer kareem 3,303 Views • 2 years ago

Dumping syndrome is a condition that can develop after surgery to remove all or part of your stomach or after surgery to bypass your stomach to help you lose weight. Also called rapid gastric emptying, dumping syndrome occurs when food, especially sugar, moves from your stomach into your small bowel too quickly.Diet: Eating too much sugar can cause sugars to pass into the colon, making the bacteria there get all excited and cause diarrhea. Other things like sorbitol, a sweetener in some sugarless candy, can also cause diarrhea through osmosis. Malabsorption: Some people don't digest sugars or fats properly.

Dumping syndrome is a condition that can develop after surgery to remove all or part of your stomach or after surgery to bypass your stomach to help you lose weight. Also called rapid gastric emptying, dumping syndrome occurs when food, especially sugar, moves from your stomach into your small bowel too quickly. Most people with dumping syndrome develop signs and symptoms, such as abdominal cramps and diarrhea, 10 to 30 minutes after eating. Other people have symptoms one to three hours after eating, and still others have both early and late symptoms. Generally, you can help prevent dumping syndrome by changing your diet after surgery. Changes might include eating smaller meals and limiting high-sugar foods. In more-serious cases o

Stapled Haemorrhoidopexy
Stapled Haemorrhoidopexy samer kareem 24,405 Views • 2 years ago

A stapled haemorrhoidopexy is an operation to return the haemorrhoids to a normal. position inside the rectum (back passage). A circular shaped stapling device is gently. inserted in the back passage. The surgeon is then able to use the device to remove.

Stapled Hemorrhoidectomy
Stapled Hemorrhoidectomy samer kareem 2,131 Views • 2 years ago

Haemorrhoids is one of the most common problems seen in surgical OPD. Open haemorrhoidectomy has remained the gold standard for a long time with a high post-operative morbidity. The quest for a better understanding of the pathology of haemorrhoids resulted in the evolvement of stapler haemorrhoidopexy. Our aim is to study the efficacy of stapler haemorrhoidopexy with regards to role of immediate post-operative morbidity. A prospective study of 50 patients (n = 50) with the second- and third-degree symptomatic haemorrhoids was done. The mean age of the patients was 44.1 years. Fourteen patients had co-morbid conditions. The average duration of the operation was 29 min. Patients with the second-degree haemorrhoids had higher rate of complication. The complication rate was 32%. Three patients had urinary retention. Two patients had minor bleeding, and one patient experienced transient discharge. The mean analgesic requirement was 2.4 tramadol, 50 mg injections. Ten patients had significant post-operative pain. Average length of hospital stay was 2.7 days. There were no symptomatic recurrences till date.

Kidney Transplant & Dialysis
Kidney Transplant & Dialysis samer kareem 6,929 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.

DIALYSIS

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.

minimally invasive procedure is the new gold standard for hemorrhoidectomy, according to American and European experts in the field. The procedure, known as PPH (procedure for prolapse and hemorrhoids) stapled hemorrhoidectomy, combines hemorrhoidal devascularization and repositioning to return the veins to the anal canal. “This year, this is the revolutionary new procedure in the United States,” Gary Hoffman, MD, clinical faculty member in general and colorectal surgery, Cedars-Sinai Medical Center, Los Angeles, told General Surgery News after moderating a live PPH telesurgery at the 2003 annual meeting of the Society of American Gastrointestinal Endoscopic Surgeons.

Molar Uprighting for Implant
Molar Uprighting for Implant samer kareem 11,167 Views • 2 years ago

Aim: To detail two different clinical protocols and case studies using mini-implant anchorage developed to respond to certain clinical conditions. Methods: Two clinical protocols are described to upright mesially tilted mandibular molars. In the first protocol, a single mini-implant is inserted distally to the molar to be uprighted, and an elastic traction chain is applied to the tooth. In the second clinical approach, two mini-implants are inserted mesially. A screw-suspended TMA sectional archwire is applied (Derton-Perini technique). Two cases, descriptive of the two different treatment protocols, are described. In the first case, the mandibular right second premolar was missing and the adjacent first molar needed to be uprighted. A single screw was inserted distally to the first molar, and an elastic chain was applied. In the second case, the mandibular left second molar was missing and the third molar needed to be uprighted. Two mini-implants were inserted mesially and a fully screw-supported sectional archwire was used to upright and bodily mesialize the third molar. Results: Both uprighting approaches uprighted the molar axis without loss of anchorage. Conclusion: The two approaches to mandibular molar uprighting, developed as rational responses to different clinical cases, were both found to be effective.
