Retina Laser Surgery
Retina Laser Surgery samer kareem 1,447 Views • 2 years ago

Most retinal tears need to be treated by sealing the retina to the back wall of the eye with laser surgery or cryotherapy (a freezing treatment). Both of these procedures create a scar that helps seal the retina to the back of the eye. This prevents fluid from traveling through the tear and under the retina, which usually prevents the retina from detaching. These treatments cause little or no discomfort and may be performed in your ophthalmologist’s office. With laser surgery, your ophthalmologist uses a laser to make small burns around the retinal tear. The scarring that results seals the retina to the underlying tissue, helping to prevent a retinal detachment.

Minimally Invasive Parotidectomy
Minimally Invasive Parotidectomy samer kareem 1,987 Views • 2 years ago

Minimally invasive parotid surgery techniques are currently utilized here in Atlanta by our practice to allow the same operation to be performed with no permanent visible incision on the face or the neck. In addition to being more cosmetically appealing, this approach is less painful and allows the procedure to be performed as an outpatient. Most patients take pain medication for only a day or two after surgery.

Meniscus allograft survival in patients with moderate to severe unicompartmental arthritis: a 2- to 7-year follow-up.PURPOSE: We present meniscus allograft survival data at least 2 years from surgery for 45 patients (47 allografts) with significant arthrosis to determine if the meniscus can survive ...in an arthritic joint. Type of Study: Prospective, longitudinal survival study. METHODS: Data were collected for 31 men and 14 women, mean age 48 years (range, 14 to 69 years), with preoperative evidence of significant arthrosis and an Outerbridge classification greater than II. Failure is established by previous studies as allograft removal. No patient was lost to follow-up. RESULTS: The success rate was 42 of 47 allografts (89.4%) with a mean failure time of 4.4 years as assessed by Kaplan-Meier survival analysis. Statistical power is greater than 0.9, with alpha = 0.05 and N = 47. There was significant mean improvement in preoperative versus postoperative self-reported measures of pain, activity, and functioning, with P = .001, P = .004, and P = .001, respectively, as assessed by a Wilcoxon rank-sum test with P = .05. CONCLUSIONS: Meniscus allografts can survive in a joint with arthrosis, challenging the contraindications of age and arthrosis severity. These results compare favorably with those in previous reports of meniscus allograft survival in patients without arthrosis. LEVEL OF EVIDENCE: Level IV.

Shoulder Anatomy
Shoulder Anatomy samer kareem 8,456 Views • 2 years ago

The shoulder joint is formed where the humerus (upper arm bone) fits into the scapula (shoulder blade), like a ball and socket. Other important bones in the shoulder include: The acromion is a bony projection off the scapula. The clavicle (collarbone) meets the acromion in the acromioclavicular joint.

Multiple Myeloma Mechanism of Action
Multiple Myeloma Mechanism of Action samer kareem 1,505 Views • 2 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

Blood Viscosity
Blood Viscosity samer kareem 1,309 Views • 2 years ago

When the hematocrit rises to 60 or 70%, which it often does in polycythemia, the blood viscosity can become as great as 10 times that of water, and its flow through blood vessels is greatly retarded because of increased resistance to flow. This will lead to decreased oxygen delivery.

WHAT IS BURN DEBRIDEMENT? A burn is damage to body tissues caused by sunlight, heat, fire, electricity, friction, radiation, chemicals, hot water or steam. Burns may become infected. Infected burns and the swelling that happens as a result can cause severe damage to the organs and tissues underneath the burned area by putting pressure on the tissues, nerves, and blood vessels. To allow healthy tissue to heal and to prevent more damage or infection, burned tissue is removed in a procedure called burn debridement. Burn debridement can be done by several different methods. They include surgical, chemical, mechanical, or autolytic tissue removal. Debridement may need to be done multiple times as the burned area heals.

HIV AIDS prevention
HIV AIDS prevention Liz L 9,145 Views • 2 years ago

Over one million Americans have the sexually transmitted virus, HIV, which can lead to the deadly disease known as AIDS.
HIV can be transmitted in the sexual fluids, blood or breast milk of an infected person. HIV prevention therefore involves a wide range of activities including prevention of mother-to-child transmission, needle exchanges and harm reduction for injecting drug users, and precautions for health care workers.
