Benzodiazepines samer kareem 4,027 Views • 3 years ago

Benzodiazepines are a class of agents that work on the central nervous system, acting selectively on gamma-aminobutyric acid-A (GABA-A) receptors in the brain. GABA is a neurotransmitter that inhibits or reduces the activity of nerve cells (neurons) within the brain. Benzodiazepines open GABA-activated chloride channels, and allow chloride ions to enter the neuron. This makes the neuron negatively charged and resistant to excitation.

Progeria
Progeria samer kareem 5,500 Views • 3 years ago

Progeria (pro-JEER-e-uh), also known as Hutchinson-Gilford syndrome, is an extremely rare, progressive genetic disorder that causes children to age rapidly, beginning in their first two years of life. Children with progeria generally appear normal at birth. During the first year, signs and symptoms, such as slow growth and hair loss, begin to appear. Heart problems or strokes are the eventual cause of death in most children with progeria. The average life expectancy for a child with progeria is about 13 years, but some with the disease die younger and some live 20 years or longer. There's no cure for progeria, but ongoing research shows some promise for treatment.

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

Henoch-Schonlein Purpura samer kareem 1,616 Views • 3 years ago

Temporal arteritis is a condition in which the temporal arteries, which supply blood to the head and brain, become inflamed or damaged. It is also known as cranial arteritis or giant cell arteritis. Although this condition usually occurs in the temporal arteries, it can occur in almost any medium to large artery in the body. The journal Arthritis & Rheumatology states that approximately 228,000 people in the United States are affected by temporal arteritis. According to the American College of Rheumatology, people over the age of 50 are more likely than younger people to develop the condition. Women are also more likely than men to have temporal arteritis. It is most prevalent in people of northern European or Scandinavian descent. Although the exact cause of the condition is unknown, it may be linked to the body’s autoimmune response. Also, excessive doses of antibiotics and certain severe infections have been linked to temporal arteritis. There’s no known prevention. However, once diagnosed, temporal arteritis can be treated to minimize complications.

Liver Absces Drainage
Liver Absces Drainage samer kareem 1,463 Views • 3 years ago

Bacterial abscess of the liver is relatively rare; however, it has been described since the time of Hippocrates (400 BCE), with the first published review by Bright appearing in 1936. In 1938, Ochsner's classic review heralded surgical drainage as the definitive therapy; however, despite the more aggressive approach to treatment, the mortality remained at 60-80%. [1] The development of new radiologic techniques, the improvement in microbiologic identification, and the advancement of drainage techniques, as well as improved supportive care, have reduced mortality to 5-30%; yet, the prevalence of liver abscess has remained relatively unchanged. Untreated, this infection remains uniformly fatal.
