Cortisol and Glucocorticoids
Cortisol and Glucocorticoids samer kareem 3,618 Views • 2 years ago

The vast majority of glucocorticoid activity in most mammals is from cortisol, also known as hydrocortisone. Corticosterone, the major glucocorticoid in rodents, is another glucocorticoid. Cortisol binds to the glucocorticoid receptor in the cytoplasm and the hormone-receptor complex is then translocated into the nucleus, where it binds to its DNA response element and modulates transcription from a battery of genes, leading to changes in the cell's phenotype. Only about 10% of circulating cortisol is free. The remaining majority circulates bound to plasma proteins, particularly corticosteroid-binding globulin (transcortin). This protein binding likely decreases the metabolic clearance rate of glucocorticoids and, because the bound steroid is not biologically active, tends to act as a buffer and blunt wild fluctuations in cortisol concentration.

What we do for massive lymphedema ? samer kareem 1,772 Views • 2 years ago

The lymphatic system is a network of specialized vessels (lymph vessels) throughout the body whose purpose is to collect excess lymph fluid with proteins, lipids, and waste products from the tissues. This fluid is then carried to the lymph nodes, which filter waste products and contain infection-fighting cells called lymphocytes. The excess fluid in the lymph vessels is eventually returned to the bloodstream. When the lymph vessels are blocked or unable to carry lymph fluid away from the tissues, localized swelling (lymphedema) is the result.

What is Lymphoedema ?
What is Lymphoedema ? samer kareem 1,352 Views • 2 years ago

The condition is caused by a blockage in the lymphatic system, part of the immune and circulatory systems. Lymphedema is most commonly caused by lymph node removal or damage due to cancer treatment. The main symptom is swelling in an arm or leg that may be accompanied by pain or discomfort. Exercise, wrapping, massage, and compression can help.

Wernicke-Korsakoff Syndrome
Wernicke-Korsakoff Syndrome samer kareem 5,064 Views • 2 years ago

-Korsakoff's syndrome is a common and preventable sequel of Wernicke's encephalopathy. Thiamine, if given during the stage of Wernicke's encephalopathy, can prevent the onset of Korsakoff's psychosis. The administration of glucose prior to thiamine can precipitate Korsakoff's syndrome, as seen in this case. In such patients, brain MRI frequently shows abnormal enhancement of the mammillary bodies & thallamus

Diplegic Gait Demonstration
Diplegic Gait Demonstration samer kareem 1,834 Views • 2 years ago

The patient has spasticity in the lower extremities greater than the upper extremities. The hips and knees are flexed and adducted with the ankles extended and internally rotated. When the patient walks both lower extremities are circumducted and the upper extremities are held in a mid or low guard position. This type of gait is usually seen with bilateral periventricular lesions. The legs are more affected than the arms because the corticospinal tract axons that are going to the legs are closest to the ventricles.
