Nerve Root Block Injection Procedure
Nerve Root Block Injection Procedure samer kareem 6,405 Views • 2 years ago

A nerve root block is an injection of local anesthetic (numbing medicine) and steroid injected under X-ray guidance into the area where the nerve exits the spinal column. A nerve root block is usually ordered by your doctor for pain in the arm or leg that follows the path of a single nerve. A nerve root block may be diagnostic (a test to determine the source of your pain) and/or therapeutic (to relieve your pain). If you get a period of sustained pain relief from the injection, the block may be repeated. Sometimes the block is done to help identify whether or not surgery might be helpful and at what level such surgery might be most helpful.

Bone Tumor. Reasons
Bone Tumor. Reasons samer kareem 5,807 Views • 2 years ago

Bone tumors develop when cells in the bone divide without control, forming a mass of tissue. Most bone tumors are benign, which means they are not cancer and cannot spread. However, they may still weaken bone and lead to fractures or cause other problems. Bone cancer destroys normal bone tissue and may spread to other parts of the body (called metastasis). Benign Bone Tumors Benign tumors are more common than malignant tumors of the bones. These are a few common types of benign bone tumors: Osteochondroma is the most common benign bone tumor. It is more common in people under age 20. Giant cell tumor is a benign tumor, typically affecting the leg (malignant types of this tumor are uncommon). Osteoid osteoma is a bone tumor, often occurring in long bones, that occurs commonly in the early 20s. Osteoblastoma is a single tumor that occurs in the spine and long bones, mostly in young adults. Enchondroma usually appears in bones of the hand and feet. It often has no symptoms. It is the most common type of hand tumor.

Trigger Finger
Trigger Finger samer kareem 18,545 Views • 2 years ago

Trigger finger, also known as stenosing tenosynovitis (stuh-NO-sing ten-o-sin-o-VIE-tis), is a condition in which one of your fingers gets stuck in a bent position. Your finger may straighten with a snap — like a trigger being pulled and released. Trigger finger occurs when inflammation narrows the space within the sheath that surrounds the tendon in the affected finger. If trigger finger is severe, your finger may become locked in a bent position. People whose work or hobbies require repetitive gripping actions are at higher risk of developing trigger finger. The condition is also more common in women and in anyone with diabetes. Treatment of trigger finger varies depending on the severity.

Microscopic polyangiitis (MPA) is vasculitis of small vessels. It was initially considered as a microscopic form of polyarteritis nodosa (PAN). In 1990, the American College of Rheumatology developed classification criteria for several types of systemic vasculitis but did not distinguish between polyarteritis nodosa and microscopic polyarteritis nodosa. [1] In 1994, a group of experts held an international consensus conference in Chapel Hill, North Carolina, to attempt to redefine the classification of small vessel vasculitides. [2, 3]

How is HIV Transmitted?
How is HIV Transmitted? samer kareem 1,536 Views • 2 years ago

-Almost all the cases of occupational transmission of HIV have been due to transmission via exposure to blood and certain body fluids. The body fluids wherein standard precautions have been recommended include semen, vaginal secretions, and any other body fluid containing visible blood. Other standard precautions, according to the Center for Disease Control and Prevention (CDC), also apply to cerebrospinal, peritoneal, pleural, pericardia!, synovial fluid, or any other tissue, even though the epidemiologic data regarding the risk of HIV transmission from these fluids is insufficient. Standard precautions do not apply to urine, sweat, tears, sputum, vomitus, and nasal secretions or feces, as long as there is no gross visible blood. The occupational transmission of HIV has never been documented from the above sources.

-Rectocele is a relatively common condition in older women and is characterized by the displacement of the rectum through posterior vaginal wall defect(s).

Women with symptomatic rectoceles who are poor surgical candidates may be treated with pessaries, which are structures designed to support the vaginal wall.

One of the criteria to determine brain death is the irreversible absence of cerebral and brainstem reflexes including pupillary, oculocephalic, oculovestibular (caloric), corneal, gag, sucking, swallowing, and extensor posturing. Some of the other criteria for determination of brain death include: 1. Absence of respiratory drive (apnea) off the ventilator for a duration that is sufficient to produce hypercarbic drive (usually 10 to 20 minutes to achieve pC02 of 50 to 60 mmHg) ( 2. Body temperature below 34 C (93.2 F) 3. EEG isoelectric for 30 minutes at maximal gain 4. Absence of cerebral circulation by Doppler or magnetic resonance angiography 5.

Jaw surgery, also known as orthognathic (or-thog-NATH-ik) surgery, corrects irregularities of the jaw bones and realigns the jaws and teeth to improve the way they work. Making these corrections may also improve your facial appearance. Jaw surgery may be a corrective option if you have jaw problems that can't be resolved with orthodontics alone. In most cases, you also have braces on your teeth before surgery and during recovery after surgery until healing and alignment are complete. Your orthodontist can work with your oral and jaw and face (maxillofacial) surgeon to determine your treatment plan.
