CROUP
CROUP samer kareem 1,695 Views • 3 years ago

Croup refers to an infection of the upper airway, which obstructs breathing and causes a characteristic barking cough. The cough and other symptoms of croup are the result of swelling around the vocal cords (larynx), windpipe (trachea) and bronchial tubes (bronchi). When a cough forces air through this narrowed passage, the swollen vocal cords produce a noise similar to a seal barking. Likewise, taking a breath often produces a high-pitched whistling sound (stridor). Croup typically occurs in younger children. Croup usually isn't serious and most cases can be treated at home.

Spinal cord injury. Symptoms
Spinal cord injury. Symptoms samer kareem 3,681 Views • 3 years ago

Though you might think of your spinal cord as one single piece, it's actually a column of nerves protected by a sheath of myelin and then further secured by 31 butterfly-shaped vertebrae (singular: vertebra). Medical providers divide the spinal cord into four distinct regions. Knowing the region in which the injury is located is often the key to understanding diagnosis and treatment. The four spinal cord regions are: The cervical spinal cord: This is the topmost portion of the spinal cord, where the brain connects to the spinal cord, and the neck connects to the back. This region consists of eight vertebrae, commonly referred to as C1-C8. All spinal cord numbers are descending, so C1 is the highest vertebra, while C8 is the lowest in this region. The thoracic spinal cord: This section forms the middle of the spinal cord, containing twelve vertebrae numbered T1-T12.

Complete cardiac transplant
Complete cardiac transplant samer kareem 7,681 Views • 3 years ago

The first operation is harvesting the heart from the donor. The donor is usually an unfortunate person who has suffered irreversible brain injury, called "brain death". Very often these are patients who have had major trauma to the head, for example, in an automobile accident. The victim's organs, other than the brain, are working well with the help of medications and other "life support" that may include a respirator or other devices. A team of physicians, nurses, and technicians goes to the hospital of the donor to remove donated organs once brain death of the donor has been determined. The removed organs are transported on ice to keep them alive until they can be implanted. For the heart, this is optimally less than six hours. So, the organs are often flown by airplane or helicopter to the recipient's hospital.
