Multiple Myeloma Mechanism of Action
Multiple Myeloma Mechanism of Action samer kareem 1,546 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 It was withdrawn from the market in 1961 because of its teratogenic effects.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

Acute kidney injury: mechanism, diagnosis and management
Acute kidney injury: mechanism, diagnosis and management samer kareem 1,544 Views • 3 years ago

Acute kidney injury is common entity in medical practice. The present definition is based on a serum creatinine rise of more 0.3 mg/dl in 48 hours or less, a 50% increase from the baseline over a period of 07 days or a urine output of less than 0.5 ml/kg/hour for more than 06 hours. The main causes of acute kidney injury may be classified into pre renal, intrinsic or post renal causes. Rapid diagnosis and prompt treatment is essential to prevent mortality or morbidity. This presentation discusses in detail the causes of all three mechanisms, pre-renal, post renal and intrinsic.

Is oncology the right choice for you? samer kareem 1,543 Views • 3 years ago

What combines research opportunities, intellectual challenge, and international collaboration in the study of a disease which affects many organs of the body and all sectors of society? And demands that specialists from many different backgrounds work together to crack sometimes intractable problems? It is, of course, oncology. As a career choice, it's demanding; it takes passion coupled with a willingness to put in the hours and to learn how to discuss death honestly and sensitively. But for the right person, it can be immensely rewarding.

Systemic lupus erythematous is an autoimmune condition characterised by damage to organ systems due to autoantibodies and immune complex deposition. Genes, epigenetic changes and environment play a role in its pathogenesis. SLE is a truly multi system disease causing widespread clinical manifestations in almost all organ systems. Autoantibodies in SLE are numerous and mainly include ANA, dsDNA, Sm and others.

Biceps tenodesis is a common procedure performed for tendinopathy of the long head of the biceps brachii (LHB). Indications include partial-thickness LHB tear, tendon subluxation with or without subscapularis tear, and failed conservative management of bicipital tenosynovitis. Biceps tenodesis may also be performed for superior labrum anterior to posterior tears.

Lactose Intolerance
Lactose Intolerance samer kareem 1,541 Views • 3 years ago

People with lactose intolerance are unable to fully digest the sugar (lactose) in milk. As a result, they have diarrhea, gas and bloating after eating or drinking dairy products. The condition, which is also called lactose malabsorption, is usually harmless, but its symptoms can be uncomfortable. A deficiency of lactase — an enzyme produced in your small intestine — is usually responsible for lactose intolerance. Many people have low levels of lactase but are able to digest milk products without problems. If you're actually lactose intolerant, though, your lactase deficiency leads to symptoms after you eat dairy foods.

Tourette's Syndrome
Tourette's Syndrome samer kareem 1,540 Views • 3 years ago

Tourette syndrome (also called Tourette's disorder or simply, "Tourette's") is an abnormal neurological condition characterized by motor and vocal tics. Tics are involuntary, rapid, sudden repetitive movements or sounds. Tics can be classified in a variety of ways. Motor tics can affect any part of the body including the head, neck, face, arms, shoulders, hands, feet, or legs. Facial tics, especially eye blinking, are usually the first symptoms of TS. Vocal tics are sounds that are made involuntarily. Vocal tics can include clearing the throat, coughing, sniffing, grunting, yelping, or shouting. In a few cases, vocal tics can include strange, inappropriate, or obscene words and phrases (called coprolalia). Vocal tics can also appear as constantly repeating the words of others (echolalia).

Carpal tunnel syndrome is a hand condition that causes numbness, tingling and other symptoms. Carpal tunnel syndrome is caused by a pinched nerve in your wrists A number of factors can contribute to carpal tunnel syndrome, including the anatomy of your wrist, certain underlying health problems and possibly patterns of hand use. Bound by bones and ligaments, the carpal tunnel is a narrow passageway located on the palm side of your wrist. This tunnel protects a main nerve to your hand and the nine tendons that bend your fingers. Compression of the nerve produces the numbness, tingling and, eventually, hand weakness that characterize carpal tunnel syndrome.

Strep Throat to Rheumatic Heart Disease
Strep Throat to Rheumatic Heart Disease samer kareem 1,538 Views • 3 years ago

What causes rheumatic fever? Rheumatic fever is not an infection itself, but rather the result of an untreated strep infection. When your body senses the strep infection, it sends antibodies to fight it. Sometimes, these antibodies attack the tissues of your joints or heart instead. If the antibodies attack your heart, they can cause your heart valves to swell, which can lead to scarring of the valve "doors" (called leaflets or cusps). Who is at risk for rheumatic fever? Fewer than 0.3% of people who have strep throat also get rheumatic fever. Rheumatic fever is most common among children aged 5 to 15, but adults may have the condition as well. Doctors think that a weakened immune system may make some people more likely to get rheumatic fever. And, although antibiotic medicines have reduced the number of cases of rheumatic fever in developed countries, there are still thousands of reported cases. What are the symptoms of rheumatic fever and how is it diagnosed? Symptoms of rheumatic fever usually begin 1 to 6 weeks after you have had a strep infection. They are Fever Joint pain or swelling in your wrists, elbows, knees, or ankles Small bumps under the skin over your elbows or knees (called nodules) A raised, red rash on your chest, back, or stomach Stomach pain or feeling less hungry Weakness, shortness of breath, or feeling very tired Your doctor will begin by doing a throat culture to find out if you have a strep infection. Then, your doctor will use a stethoscope to listen to your heart. He or she will also look for nodules on your joints. Sometimes, blood tests, chest x-rays, or an electrocardiogram (ECG or EKG) may be needed for a more definite diagnosis. How is rheumatic fever treated? Rheumatic fever must be treated right away. If you have a sore throat that lasts longer than 3 days, or if you have a fever and headache along with your sore throat, you should see your doctor for a throat culture. Even if you do not have a sore throat but have a fever and a skin rash, this could also mean a strep infection, and you should get tested. Remember rheumatic fever can result from an untreated strep infection, so it is very important to treat the infection before it leads to a worse condition.
