How Old Are Your Ears?
How Old Are Your Ears? samer kareem 5,162 Views • 3 years ago

Hearing loss can affect anyone at any age, due to heredity, medical conditions or loud noise exposure. However, as we get older, we naturally become more susceptible to hearing loss because of changes to the delicate mechanics of our ears.

Laparoscopic Sigmoid Colectomy
Laparoscopic Sigmoid Colectomy samer kareem 2,532 Views • 3 years ago

This operation can be performed as an open or laparoscopic (keyhole procedure). During the operation the sigmoid colon is removed. This involves taking away the blood vessels and lymph nodes to that part of the bowel. The surgeon then re-makes the join (anastomosis) between the remaining left side of the colon and the top of the rectum. The surgeon may use either sutures or special staples to make this join.

Multiple Myeloma Mechanism of Action
Multiple Myeloma Mechanism of Action samer kareem 1,533 Views • 3 years ago

The pathobiology of MM is complex and the root underlying cause of myeloma is the multistep genetic changes in the postgerminal center B cell. In addition, the bone marrow microenvironment plays a crucial role.[2] The interaction between myeloma cells and the microenvironment is mediated through adhesive interactions via cell-surface receptors, paracrine loops involving several cytokines, such as IL-6, VEGF and IL-10, and suppression of cell-mediated immunity.[2–4] IMiDs modulate many of these interactions leading to decreased myeloma cell growth and survival. Thalidomide was the first IMiD introduced to treat MM. It was initially synthesized in Germany in the late 1950s to treat insomnia and morning sickness. It was withdrawn from the market in 1961 because of its teratogenic effects. Its immunomodulatory properties were realized when it was observed to improve erythema nodosum leprosum, a painful immunologic reaction of leprosy, leading to its approval by the FDA in 1998 with tight prescribing and marketing regulations. Subsequent research showed the diverse mechanism of action of thalidomide including its immunomodulatory effect by inhibition of de novo IgM antibody synthesis,[5] modulation of the T-cell subset by increasing the T-helper cells, inhibitory effects on the TNF-α and antiangiogenic activity leading to its use in MM. Significantly higher response rates in combination with dexamethasone led to its approval in the treatment of newly diagnosed MM in 2006. Lenalidomide, a second-generation IMiD, was developed from the structural backbone of the thalidomide molecule by the addition of an amino group (NH2-) at position 4 of the phthaloyl ring and removal of the carbonyl group (C = O) of the 4-amino-substituted phthaloyl ring (Table 1).[6] In addition to immunomodulatory effects, other mechanisms of action have been described such as direct cytotoxicity via induction of apoptosis, inhibition of cell adhesion molecules and inhibition of growth signals that promote bone marrow angiogenesis

wisdom teeth removal - surgery,extraction
wisdom teeth removal - surgery,extraction samer kareem 3,304 Views • 3 years ago

Simply put, there isn’t enough room for wisdom teeth because our jaws don’t grow to be big enough to have enough space for them to come in. Since there isn’t enough room for them to erupt properly, wisdom teeth tend to come in at an angle or they don’t fully emerge, which causes problems for the rest of the mouth. Third molars (the wisdom teeth) routinely damage the teeth right next door, called second molars. Dentists recommend removing wisdom teeth before they become a problem and to avoid a more complicated surgery. Read more at Ask the Dentist: https://askthedentist.com/wisdom-teeth-removal/

Artificial Kidney Transplant

The anatomy of the ureter
The anatomy of the ureter samer kareem 7,091 Views • 3 years ago

Pelvic ureter. The ureter enters the pelvis, where it crosses anteriorly to the iliac vessels, which usually occurs at the bifurcation of the common iliac artery into the internal and external iliac arteries. Here, the ureters are within 5 cm of one another before they diverge laterally.

Bowel Obstruction Symptoms
Bowel Obstruction Symptoms samer kareem 2,070 Views • 3 years ago

What could cause a blockage in the stomach? Mechanical causes of intestinal obstruction may include: Adhesions or scar tissue that forms after surgery. Foreign bodies (objects that are swallowed and block the intestines) Gallstones (rare) Hernias. Impacted stool. Intussusception (telescoping of one segment of bowel into another) Tumors blocking the intestines. Less common radiologic signs are seen in specific circumstances. Most closed-loop obstructions (75%) are caused by adhesions. A closed-loop obstruction occurs when a loop of bowel is not decompressed by the caudal passage of gas and fluid.

Isolated sphenoidal sinusitis
Isolated sphenoidal sinusitis samer kareem 5,003 Views • 3 years ago

Results Sinusitis was characterized as acute in 26 patients, subacute in 5 (including 1 pyocele), and chronic in 8 (including 2 fungal infections). No tumors were found. Isolated sinus cysts were excluded from the study. Headache, the main symptom in 32 patients (82%), was localized most commonly on the vertex. Other common complaints were rhinitis, dizziness, eye symptoms, and fever. In 2 patients, the finding was occult. Eight patients (21%) presented with cranial nerve deficits, and 1 patient had an intracranial complication. Sinus irrigation was performed in 16 patients (41%) and sphenoidotomy was performed in 10 (26%). Fifteen patients (38%) were treated with antibiotic drugs alone. Within 3 months, 31 (84%) of 37 patients had recovered from the illness; 5 still experienced headaches despite having normalized radiographic findings; and 1 had permanent unilateral visual loss. Two patients were lost to follow-up.

Waardenburg Syndrome
Waardenburg Syndrome samer kareem 2,271 Views • 3 years ago

Waardenburg syndrome is a group of genetic conditions that can cause hearing loss and changes in coloring (pigmentation) of the hair, skin, and eyes. Although most people with Waardenburg syndrome have normal hearing, moderate to profound hearing loss can occur in one or both ears. The hearing loss is present from birth (congenital). People with this condition often have very pale blue eyes or different colored eyes, such as one blue eye and one brown eye. Sometimes one eye has segments of two different colors. Distinctive hair coloring (such as a patch of white hair or hair that prematurely turns gray) is another common sign of the condition. The features of Waardenburg syndrome vary among affected individuals, even among people in the same family.
