Acute kidney injury: mechanism, diagnosis and management
Acute kidney injury: mechanism, diagnosis and management samer kareem 1,516 Views • 2 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.

The primary goal of treatment for each patient is to help relieve pain and other symptoms resulting from the herniated disc. To achieve this goal, each patient’s treatment plan should be individualized based on the source of the pain, the severity of pain and the specific symptoms that the patient exhibits.

Tourette's Syndrome
Tourette's Syndrome samer kareem 1,514 Views • 2 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).

Microsurgical Suturing
Microsurgical Suturing samer kareem 1,513 Views • 2 years ago

At first, grasping the needle is difficult because it will have a tendency to want to jump around. What can oftentimes help is to get hold of the thread with the left-hand forceps at a point 2 to 3 cm away from the needle. Dangle the needle until it just comes to rest on the surface. This will then allow you to use the angulated needle holder to grab the needle easily. Your needle is in a stable position if it is set up to 90 degrees to the axis of the tips of the forceps. You can make minor corrections by touching the needle with your left-hand forceps, or by partially relaxing your grip and nudging the needle tip against another firm object. You should hold the needle just behind its midpoint (If you hold it too near the tip, it will point downward. If you hold it too near the thread end, it will point upward.).

Multiple Myeloma Mechanism of Action
Multiple Myeloma Mechanism of Action samer kareem 1,513 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

A hematoma is a common complication of surgical procedures. A large, expanding hematoma can result in necrosis of the overlying skin (1,2) or adjacent subcutaneous fat, increased incidence of infection, scarring, skin hyperpigmentation, tissue edema and a prolonged convalescence.

Pneumoconiosis is a general term given to any lung disease caused by dusts that are breathed in and then deposited deep in the lungs causing damage. Pneumoconiosis is usually considered an occupational lung disease, and includes asbestosis, silicosis and coal workers' pneumoconiosis (CWP), also known as "Black Lung Disease."

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.

Reverse shoulder arthroplasty

Every year, thousands of conventional total shoulder replacements are successfully done in the United States for patients with shoulder arthritis. This type of surgery, however, is not as beneficial for patients with large rotator cuff tears who have developed a complex type of shoulder arthritis called "cuff tear arthropathy." For these patients, conventional total shoulder replacement may result in pain and limited motion, and reverse total shoulder replacement is a better option.

Is oncology the right choice for you? samer kareem 1,505 Views • 2 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.
