Rabies
Rabies samer kareem 7,262 Views • 2 years ago

In developing countries, domestic animals (eg, dogs) are common sources of infection. In the United States, bats and wild animals (eg, raccoons) are the most common reservoirs of infection. The acquisition of rabies from bats can occur from an unrecognized bite or a scratch, and possibly by inhalation of aerosolized viral particles. Bats are found in all states except Hawaii, and spelunking (cave exploration) is a risk factor for rabies acquisition from bats.

Bilateral renal agenesis (BRA) is the absence of both kidneys. Both types of renal agenesis occur in fewer than 1 percent of births annually, according to the March of Dimes. Fewer than 1 in every 1,000 newborns has URA. BRA is much rarer, occurring in about 1 in every 3,000 births.

Genetic Disorders And Diseases
Genetic Disorders And Diseases samer kareem 4,446 Views • 2 years ago

Genes are the building blocks of heredity. They are passed from parent to child. They hold DNA, the instructions for making proteins. Proteins do most of the work in cells. They move molecules from one place to another, build structures, break down toxins, and do many other maintenance jobs. Sometimes there is a mutation, a change in a gene or genes. The mutation changes the gene's instructions for making a protein, so the protein does not work properly or is missing entirely. This can cause a medical condition called a genetic disorder. You can inherit a gene mutation from one or both parents. A mutation can also happen during your lifetime.

Anti-phospholipid Syndrome
Anti-phospholipid Syndrome samer kareem 1,761 Views • 2 years ago

Antiphospholipid (AN-te-fos-fo-LIP-id) syndrome occurs when your immune system attacks some of the normal proteins in your blood. It can cause blood clots in your arteries or veins. And it can cause pregnancy complications, such as miscarriage and stillbirth. Blood clots in your leg veins cause a condition known as deep vein thrombosis (DVT). Damage from blood clots in your organs, such as your kidneys, lungs or brain, depends on the extent and location of the clot. For instance, a clot in your brain can cause a stroke. There's no cure for antiphospholipid syndrome, but medications can reduce your risk of blood clots.

Skin Grafting in Plastic Surgery

Skin grafting is a type of medical grafting involving the transplantation of skin. The transplanted tissue is called a skin graft. Skin grafting is often used to treat: Extensive wounding or trauma Burns Areas of extensive skin loss due to infection such as necrotizing fasciitis or purpura fulminans Specific surgeries that may require skin grafts for healing to occur – most commonly removal of skin cancers. Skin grafts are often employed after serious injuries when some of the body’s skin is damaged. Surgical removal (excision or debridement) of the damaged skin is followed by skin grafting. The grafting serves two purposes: it can reduce the course of treatment needed (and time in the hospital), and it can improve the function and appearance of the area of the body which receives the skin graft. There are two types of skin grafts, the more common type is where a thin layer is removed from a healthy part of the body (the donor section), like peeling a potato, or a full thickness skin graft, which involves pitching and cutting skin away from the donor section. A full thickness skin graft is more risky, in terms of the body accepting the skin, yet it leaves only a scar line on the donor section, similar to a Cesarean section scar. For full thickness skin grafts, the donor section will often heal much more quickly than the injury and is less painful than a partial thickness skin graft.

Microvascular Anastomosis
Microvascular Anastomosis samer kareem 1,085 Views • 2 years ago

Simple microinstruments and a medical school laboratory microscope were used for anastomosis training. Chicken blood vessels were used as a material for this study. A long segment of blood vessel from the proximal brachial artery to the distal radial artery was used for training. End-to-side anastomosis was practiced first, and the training continued with end-to-end anastomosis of the appropriate segments.

The needle should pass through the tissue at a perpendiculaPlace the tips of the left-hand forceps on the underside of the tissue at the point where the needle will enter, and gently push the edge upward. With the right hand, bring the needle into contact with the tissue, and press downward. These movements create eversion. Pass the needle through. Do not grab the tissue with your left hand forceps since it will damage the intima. If needed, you can pick up adventitia or a nearby suture to help with exposure and eversion. r.The needle must pass through the other side at a perpendicular, too. Bring the tip of the needle to the place where you intend to bring it out on the other side. Put the tip of your left-hand forceps on the upper surface of the tissue at the intended exit point. Press down with the left-hand forceps and push up with the needle to give you the correct eversion. The width of the bite should be about three times the thickness of the needle. The bites on both sides must be equal, and the needle should cross exactly in a straight line (not diagonally). Pull the needle through the tissue following the curve of the needle
