HIV / AIDS
HIV / AIDS samer kareem 2,677 Views • 2 years ago

HIV stands for human immunodeficiency virus. If left untreated, HIV can lead to the disease AIDS (acquired immunodeficiency syndrome). Unlike some other viruses, the human body can’t get rid of HIV completely. So once you have HIV, you have it for life. HIV attacks the body’s immune system, specifically the CD4 cells (T cells), which help the immune system fight off infections. If left untreated, HIV reduces the number of CD4 cells (T cells) in the body, making the person more likely to get infections or infection-related cancers. Over time, HIV can destroy so many of these cells that the body can’t fight off infections and disease. These opportunistic infections or cancers take advantage of a very weak immune system and signal that the person has AIDS, the last state of HIV infection. No effective cure for HIV currently exists, but with proper treatment and medical care, HIV can be controlled. The medicine used to treat HIV is called antiretroviral therapy or ART. If taken the right way, every day, this medicine can dramatically prolong the lives of many people with HIV, keep them healthy, and greatly lower their chance of transmitting the virus to others. Today, a person who is diagnosed with HIV, treated before the disease is far advanced, and stays on treatment can live a nearly as long as someone who does not have HIV.

What is Mohs Surgery?
What is Mohs Surgery? Surgeon 77 Views • 2 years ago

Mohs surgery is a procedure used to remove skin cancers (most commonly basal and squamous cell carcinoma and melanoma) in a way that preserves a maximum amount of healthy tissue. It is useful for skin cancers when:

(1) the location of the cancer is near sensitive areas, like the fingers or face;
(2) earlier treatments have not worked;
(3) a skin cancer is large; and
(4) regular surgery is less likely to remove the cancer.

This procedure video illustrates the procedure on 2 patients with basal cell carcinoma. Click https://ja.ma/3b4scuY to learn more.

Frostbite - A Nightmare
Frostbite - A Nightmare Mohamed Ibrahim 8,341 Views • 2 years ago

Frostbite is an injury caused by freezing of the skin and underlying tissues. First your skin becomes very cold and red, then numb, hard and pale. Frostbite is most common on the fingers, toes, nose, ears, cheeks and chin. Exposed skin in cold, windy weather is most vulnerable to frostbite. But frostbite can occur on skin covered by gloves or other clothing. Frostnip, the first stage of frostbite, doesn't cause permanent skin damage. You can treat very mild frostbite with first-aid measures, including rewarming your skin. All other frostbite requires medical attention because it can damage skin, tissues, muscle and bones. Possible complications of severe frostbite include infection and nerve damage.

Marfan Syndrome Diagnosis and Treatment
Marfan Syndrome Diagnosis and Treatment samer kareem 9,822 Views • 2 years ago

Marfan syndrome is a genetic disorder that affects the body’s connective tissue. Connective tissue holds all the body’s cells, organs and tissue together. It also plays an important role in helping the body grow and develop properly. marfan_general_2.jpg What is Marfan Syndrome?Connective tissue is made up of proteins. The protein that plays a role in Marfan syndrome is called fibrillin-1. Marfan syndrome is caused by a defect (or mutation) in the gene that tells the body how to make fibrillin-1. This mutation results in an increase in a protein called transforming growth factor beta, or TGF-β. The increase in TGF-β causes problems in connective tissues throughout the body, which in turn creates the features and medical problems associated with Marfan syndrome and some related disorders. Because connective tissue is found throughout the body, Marfan syndrome can affect many different parts of the body, as well. Features of the disorder are most often found in the heart, blood vessels, bones, joints, and eyes. Some Marfan features – for example, aortic enlargement (expansion of the main blood vessel that carries blood away from the heart to the rest of the body) – can be life-threatening. The lungs, skin and nervous system may also be affected. Marfan syndrome does not affect intelligence.

Skin Grafting  Procedure
Skin Grafting Procedure samer kareem 19,377 Views • 2 years ago

This surgery is usually done while you are under general anesthesia. That means you will be asleep and pain-free. Healthy skin is taken from a place on your body called the donor site. Most people who are having a skin graft have a split-thickness skin graft. This takes the two top layers of skin from the donor site (the epidermis) and the layer under the epidermis (the dermis). The donor site can be any area of the body. Most times, it is an area that is hidden by clothes, such as the buttock or inner thigh. The graft is carefully spread on the bare area where it is being transplanted. It is held in place either by gentle pressure from a well-padded dressing that covers it, or by staples or a few small stitches. The donor-site area is covered with a sterile dressing for 3 to 5 days. People with deeper tissue loss may need a full-thickness skin graft. This requires an entire thickness of skin from the donor site, not just the top two layers. A full-thickness skin graft is a more complicated procedure. Common donor sites for full-thickness skin grafts include the chest wall, back, or abdominal wall.

This surgery may be done if a part of your body has lost its protective covering of skin due to burns, injury, or illness. Skin grafts are performed in a hospital. Most skin grafts are done using general anesthesia, which means you’ll be asleep throughout the procedure and won’t feel any pain.
