The liver also detoxifies chemicals and metabolizes drugs. As it does so, the liver secretes bile that ends up back in the intestines. The liver also makes proteins important for blood clotting and other functions. First, for those impatient, short answers to the mini-questions (if you're reading this in the news feed, you may want to click through for the question details): No one knows why we evolved 2 kidneys and one liver.

Aortic Valve Tumor
Aortic Valve Tumor samer kareem 1,903 צפיות • לִפנֵי 2 שנים

Papillary fibroelastoma is the third most common primary tumor of the heart and is most likely to involve the cardiac valves. Like myxomas, they arise from the endocardium in most patients and since these tumors are often incidental findings at echocardiography or autopsy, the true incidence is difficult to estimate. Most patients are older than 60 years, which also contrasts with myxomas. Papillary fibroelastomas can embolize, leading to severe neurological complications and therefore, surgical removal is advised, although there is controversy regarding small incidental lesions and the need for surgery.

Constitutional Puberty Delay
Constitutional Puberty Delay samer kareem 4,047 צפיות • לִפנֵי 2 שנים

Delayed puberty is defined as the absence of any signs suggestive of puberty by 14 years of age. In this case, the patient's pubertal delay appears to be constitutional because of his positive family history, absence of syndromic features or systemic illness, and bone age of 12 years. Puberty correlates more closely with bone age than chronological age. On follow-up, the patient will most likely demonstrate a similar onset of puberty as his father.

Diabetes Pathophysiology
Diabetes Pathophysiology samer kareem 6,392 צפיות • לִפנֵי 2 שנים

When food is taken, it is broken down into smaller components. Sugars and carbohydrates are thus broken down into glucose for the body to utilize them as an energy source. The liver is also able to manufacture glucose. In normal persons the hormone insulin, which is made by the beta cells of the pancreas, regulates how much glucose is in the blood. When there is excess of glucose in blood, insulin stimulates cells to absorb enough glucose from the blood for the energy that they need. Insulin also stimulates the liver to absorb and store any excess glucose that is in the blood. Insulin release is triggered after a meal when there is a rise in blood glucose. When blood glucose levels fall, during exercise for example, insulin levels fall too. High insulin will promote glucose uptake, glycolysis (break down of glucose), and glycogenesis (formation of storage form of glucose called glycogen), as well as uptake and synthesis of amino acids, proteins, and fat. Low insulin will promote gluconeogenesis (breakdown of various substrates to release glucose), glycogenolysis (breakdown of glycogen to release gluose), lipolysis (breakdown of lipids to release glucose), and proteolysis (breakdown of proteins to release glucose). Insulin acts via insulin receptors.

Cardiovascular Examination - Clinical Examination of the Heart
Cardiovascular Examination - Clinical Examination of the Heart DrPhil 39 צפיות • לִפנֵי 2 שנים

A successful cardiovascular exam includes visual examination, palpation of the apical impulse, auscultation of Erb's point, auscultation of the carotids, and auscultation over the four different heart valve locations (aortic, pulmonic, tricuspid, and mitral). Additionally, the radial pulse is palpated while auscultating to distinguish whether a murmur is diastolic or systolic.

Parathyroid Surgery
Parathyroid Surgery samer kareem 15,648 צפיות • לִפנֵי 2 שנים

Surgery is the only way to treat parathyroid disease (hyperparathyroidism). There are no medications or pills that work to cure or treat parathyroid problems or high calcium. The parathyroid tumor must be removed by a surgeon. As soon as the parathyroid tumor has been removed, you are cured! It is very likely this will change your life. If you have hyperparathyroidism you need to have parathyroid surgery. If you have an expert surgeon this operation should be very easy.

Worst Eye Abscess

When foreign organisms such as bacteria enter the body, the immune system sends white blood cells to fight the infection. This causes swelling (inflammation) at the site of infection and the death of nearby tissue, creating a hole called a cavity, which fills with pus to form an abscess.

Genital warts Prevention samer kareem 6,239 צפיות • לִפנֵי 2 שנים

Genital warts are growths on the skin of the genital area and around the anus. They are caused by certain types of the human papilloma virus (HPV). There are more than 100 types of HPV. Some types of HPV produce warts on different parts of the body, like plantar warts on the feet and common hand warts. There is no specific treatment for HPV, but there are treatments for health problems caused by HPV. Genital warts can be treated by your healthcare provider, or with prescription medication. HPV-related cancers are more treatable when diagnosed and treated promptly. For more information, visit www.cancer.org.

-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
