CERVICAL RIB samer kareem 3,260 Views • 3 years ago

A cervical rib in humans is an extra rib which arises from the seventh cervical vertebra. Sometimes known as "neck ribs", their presence is a congenital abnormality located above the normal first rib. A cervical rib is estimated to occur in 0.2% (1 in 500 people) to 0.5% of the population.

ALPHA & BETA BLOCKERS
ALPHA & BETA BLOCKERS samer kareem 4,124 Views • 3 years ago

Alpha blockers relax certain muscles and help small blood vessels remain open. They work by keeping the hormone norepinephrine (noradrenaline) from tightening the muscles in the walls of smaller arteries and veins, which causes the vessels to remain open and relaxed. This improves blood flow and lowers blood pressure.

Tracheotomy Procedure for Airway- 3D Medical Animation
Tracheotomy Procedure for Airway- 3D Medical Animation Scott 16,633 Views • 3 years ago

A tracheotomy or a tracheostomy: is simply an opening surgically created through the neck into the trachea (windpipe) to allow direct access to the breathing tube and is commonly done in an operating room under general anesthesia. A tube is usually placed through this opening to provide an airway and to remove secretions from the lungs. Breathing is done through the tracheostomy tube rather than through the nose and mouth. The term “tracheotomy” refers to the incision into the trachea (windpipe) that forms a temporary or permanent opening, which is called a “tracheostomy,” however; the terms are sometimes used interchangeably.

Bone Anchored Hearing Aid-BAHA Implant Surgery
Bone Anchored Hearing Aid-BAHA Implant Surgery samer kareem 4,266 Views • 3 years ago

A bone-anchored hearing aid (BAHA) or bone-anchored hearing device,is a type of hearing aid based on bone conduction. It is primarily suited for people who have conductive hearing losses, unilateral hearing loss, single-sided deafness and people with mixed hearing losses who cannot otherwise wear 'in the ear' or 'behind the ear' hearing aids. They are more expensive than conventional hearing aids, and their placement involves invasive surgery which carries a risk of complications, although when complications do occur, they are usually minor. Two of the causes of hearing loss are lack of function in the inner ear(cochlea) and when the sound has problems in reaching the nerve cells of the inner ear. Example of the first include age-related hearing loss and hearing loss due to noise exposure. A patient born without external ear canals is an example of the latter for which a conventional hearing aid with a mould in the ear canal opening would not be effective. Some with this condition have normal inner ear function, as the external ear canal and the inner ear are developed at different stages during pregnancy. With normal inner anatomy, sound conducted by the skull bone improves hearing.

Anti-phospholipid Syndrome
Anti-phospholipid Syndrome samer kareem 1,803 Views • 3 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.

Lipid Lowering Agents
Lipid Lowering Agents samer kareem 2,911 Views • 3 years ago

Lipid-Lowering Agents HMG-CoA reductase inhibitors (statins) These agents inhibit the rate-limiting step in cholesterol biosynthesis by competitively inhibiting HMG-CoA reductase. Note the following: Low-density lipoprotein (LDL) reduction of 25%-60% Examples include Atorvastatin, fluvastatin, lovastatin, pitavastatin, pravastatin, rosuvastatin, simvastatin Contraindications include hypersensitivity, active liver disease, pregnancy, lactation, coadministration with strong CYP3A4 inhibitors (selected statins) Vitamin B3 Vitamin B3 inhibits very-low-density lipoprotein (VLDL) synthesis. Note the following: LDL reduction of 10% High-density lipoprotein (HDL) increase of 20% Example includes Niacin (nicotinic acid) Contraindications include hypersensitivity, liver disease, active peptic ulcer, severe hypotension, arterial bleeding Fibrates Fibrates enhance lipoprotein lipase, resulting in increased VLDL catabolism, fatty acid oxidation, and triglycerides elimination. They decrease hepatic extraction of free fatty acids. Note the following: LDL reduction of 15% Triglyceride reduction of 35% Examples include Gemfibrozil, fenofibrate, fenofibrate (micronized), fenofibric acid Contraindications include active liver disease, renal disease, primary biliary cirrhosis, gallbladder disease 2-Azetidiones These agents inhibit sterol transporter at brush border and, consequently, intestinal absorption of cholesterol. LDL reduction of 15% Example includes Ezetimibe Contraindications include hypersensitivity, coadministration with statins (if active liver disease) Bile acid sequestrants These agents lower cholesterol and LDL via bile duct sequestration. Note the following: LDL reduction of 15% Examples include Cholestyramine, colesevelam, colestipol Contraindications include biliary/bowel obstruction, serum triglycerides >300-500 mg/dL, history of hypertriglyceridemia-induced pancreatitis

HIV Virus Life Cycle and Drug Reaction
HIV Virus Life Cycle and Drug Reaction Magdy 11,487 Views • 3 years ago

Binding and Fusion: HIV begins its life cycle
when it binds to a CD4 receptor and one of two
co-receptors on the surface of a CD4+
Tlymphocyte. The virus then fuses with the host
cell. After fusion, the virus releases RNA, its
genetic material, into the host cell.

Reverse Transcription: An HIV enzyme
called reverse transcriptase converts the singlestranded HIV RNA to double-stranded HIV DNA.

Integration: The newly formed HIV DNA
enters the host cell's nucleus, where an HIV
enzyme called integrase "hides" the HIV DNA
within the host cell's own DNA. The integrated
HIV DNA is called provirus. The provirus may
remain inactive for several years, producing few or
no new copies of HIV

Transcription: When the host cell receives a
signal to become active, the provirus uses a host
enzyme called RNA polymerase to create copies of
the HIV genomic material, as well as shorter
strands of RNA called messenger RNA (mRNA).
The mRNA is used as a blueprint to make long
chains of HIV proteins.

Assembly: An HIV enzyme called protease cuts
the long chains of HIV proteins into smaller
individual proteins. As the smaller HIV proteins
come together with copies of HIV's RNA genetic
material, a new virus particle is assembled.

Budding: The newly assembled virus pushes out
("buds") from the host cell. During budding, the new
virus steals part of the cell's outer envelope. This
envelope, which acts as a covering, is studded with
protein/sugar combinations called HIV
glycoproteins. These HIV glycoproteins are
necessary for the virus to bind CD4 and coreceptors. The new copies of HIV can now move
on to infect other cells.

This is a surgery showing the removal of a large exostosis. Exostoses are bony growths in the ear canal from chronic exposure to cold water/air, most commonly from surfing. This patient had growths in both ears, which were completely obstructing the ear canals. This patient had a single exostosis that was blocking this side (the right side).

Clonidine
Clonidine samer kareem 2,227 Views • 3 years ago

Clonidine lowers blood pressure by decreasing the levels of certain chemicals in your blood. This allows your blood vessels to relax and your heart to beat more slowly and easily. The Catapres brand of clonidine is used to treat hypertension (high blood pressure). The Kapvay brand is used to treat attention deficit hyperactivity disorder (ADHD). Clonidine is sometimes given with other medications
