Whipple Robotic Surgery
Whipple Robotic Surgery samer kareem 10,283 Views • 2 years ago

Among common cancers, pancreatic cancer has one of the poorest prognoses. Because pancreatic cancer often grows and spreads long before it causes any symptoms, only about 6% of patients are still alive five years after diagnosis. For some pancreatic patients, however, a complex surgery known as the Whipple procedure may extend life and could be a potential cure. Those who undergo a successful Whipple procedure may have a five-year survival rate of up to 25%.

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.

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.

The Symptoms and Signs You May Have a Blood Clot samer kareem 1,377 Views • 2 years ago

They might not sound very life threatening, but a blood clot that develops in the deep veins of your leg, if left untreated and unable to dissolve of its own volition, may detach and travel to your lungs, causing a pulmonary embolism (or PE). In most cases, a leg blood clot will form due to lengthy periods of travel, for example if you remain immobile in cramped spaces—such as an airplane or bus—with few opportunities to stretch your legs or get up and walk around. Here are ten signs that you may have a dangerous blood clot in your leg

-Intrapartum antibiotic prophylaxis for mothers colonized with group B Streptococcus can prevent early-onset neonatal disease. Adequate prophylaxis consists of ampicillin, penicillin, or cefazolin for ;::4 hours before delivery. Regardless of intrapartum treatment, all high-risk infants must be observed for ;::49 hours. A complete blood count with differential and blood culture are indicated if the infant is preterm <37 weeks or was exposed to prolonged rupture of membranes.>18 hrs.
