Endometrial Cancer
Endometrial Cancer samer kareem 7,955 Views • 2 years ago

Endometrial cancer is a type of cancer that begins in the uterus. The uterus is the hollow, pear-shaped pelvic organ in women where fetal development occurs. Endometrial cancer begins in the layer of cells that form the lining (endometrium) of the uterus. Endometrial cancer is sometimes called uterine cancer. Other types of cancer can form in the uterus, including uterine sarcoma, but they are much less common than endometrial cancer. Endometrial cancer is often detected at an early stage because it frequently produces abnormal vaginal bleeding, which prompts women to see their doctors. If endometrial cancer is discovered early, removing the uterus surgically often cures endometrial cancer.

HIV Testing for Infants
HIV Testing for Infants samer kareem 4,285 Views • 2 years ago

Diagnosis of HIV infection in infants is aided by HIV culture or DNA/RNA polymerase chain reaction (PCR); positive results are confirmed by repeating the test. In suspected cases, HIV testing should occur in the newborn period (ie, before the infant is 48 h old), at age 1-2 months, and again at age 3-6 months.

Three cholinesterase inhibitors are commonly prescribed: Donepezil (Aricept) is approved to treat all stages of Alzheimer's. Rivastigmine (Exelon) is approved to treat mild to moderate Alzheimer's. Galantamine (Razadyne) is approved to treat mild to moderate Alzheimer's. Currently, there is no cure for Alzheimer's. But drug and non-drug treatments may help with both cognitive and behavioral symptoms. Researchers are looking for new treatments to alter the course of the disease and improve the quality of life for people with dementia. ... Medications for Memory Loss.

Causes Of Ascites
Causes Of Ascites samer kareem 2,974 Views • 2 years ago

The accumulation of ascitic fluid represents a state of total-body sodium and water excess, but the event that initiates the unbalance is unclear. Although many pathogenic processes have been implicated in the development of abdominal ascites, about 75% likely occur as a result of portal hypertension in the setting of liver cirrhosis, with the remainder due to infective, inflammatory, and infiltrative conditions. Three theories of ascites formation have been proposed: underfilling, overflow, and peripheral arterial vasodilation. The underfilling theory suggests that the primary abnormality is inappropriate sequestration of fluid within the splanchnic vascular bed due to portal hypertension and a consequent decrease in effective circulating blood volume. This activates the plasma renin, aldosterone, and sympathetic nervous system, resulting in renal sodium and water retention. The overflow theory suggests that the primary abnormality is inappropriate renal retention of sodium and water in the absence of volume depletion. This theory was developed in accordance with the observation that patients with cirrhosis have intravascular hypervolemia rather than hypovolemia. The most recent theory, the peripheral arterial vasodilation hypothesis, includes components of both of the other theories. It suggests that portal hypertension leads to vasodilation, which causes decreased effective arterial blood volume. As the natural history of the disease progresses, neurohumoral excitation increases, more renal sodium is retained, and plasma volume expands. This leads to overflow of fluid into the peritoneal cavity. The vasodilation theory proposes that underfilling is operative early and overflow is operative late in the natural history of cirrhosis. Although the sequence of events that occurs between the development of portal hypertension and renal sodium retention is not entirely clear, portal hypertension apparently leads to an increase in nitric oxide levels. Nitric oxide mediates splanchnic and peripheral vasodilation. Hepatic artery nitric oxide synthase activity is greater in patients with ascites than in those without ascites. Regardless of the initiating event, a number of factors contribute to the accumulation of fluid in the abdominal cavity. Elevated levels of epinephrine and norepinephrine are well-documented factors. Hypoalbuminemia and reduced plasma oncotic pressure favor the extravasation of fluid from the plasma to the peritoneal fluid, and, thus, ascites is infrequent in patients with cirrhosis unless both portal hypertension and hypoalbuminemia are present.

Biliary Metal Stent Placement
Biliary Metal Stent Placement samer kareem 3,741 Views • 2 years ago

The placement of a percutaneous expandable biliary endoprosthesis was first reported in 1985 by Carrasco et al. in a canine model,[1] and the endoscopic placement of expandable metal stents to relieve biliary strictures in patients was first described in 1989.[2,3] Over the past two decades, the endoscopic approach to biliary endoprosthesis placement has largely supplanted the percutaneous approach. Self-expanding metal stents (SEMS) have traditionally been used for palliation of obstructive jaundice in patients with unresectable pancreaticobiliary tumors. However, SEMS are increasingly being used in patients with resectable cancers[4] and benign biliary strictures.[5] Uncovered SEMS (uSEMS) have been shown to have longer patency periods than plastic stents when used for malignant biliary obstruction and to be cost effective if the patient's life expectancy is greater than 4–6 months.[6–8] The common causes of malignant biliary obstruction are pancreatic cancer and cholangiocarcinoma.[9–11] Biliary drainage prior to surgical resection is controversial; several investigators have reported it to be beneficial owing to the improved tissue healing with reduced bilirubin levels,[12,13] but others have also reported its deleterious effects secondary to the additional intervention..

Chordoid meningioma
Chordoid meningioma samer kareem 14,363 Views • 2 years ago

Chordoid meningioma, classified as atypical meningioma according to the World Health Organisation (WHO) classification, is a rare subtype, which represents only 0.5% of all meningiomas and is associated with a high incidence of recurrence. Multiple intracranial meningiomas are rare in non-neurofibromatosis patients. We present a female patient with both of these rare types of meningioma. The patient presented with two concurrent intracranial meningiomas, with one a meningotheliomatous subtype and the other a chordoid meningioma. Given the wide array of histological differential diagnoses in chordoid meningioma, immunohistochemistry has a significant role to play in differentiating them. Recurrence in chordoid meningioma can be generally predicted based on the extent of resection, the percentage of chordoid element, and proliferation indices.

Wilson Disease
Wilson Disease samer kareem 10,103 Views • 2 years ago

Wilson's disease is a rare inherited disorder that causes too much copper to accumulate in your liver, brain and other vital organs. Symptoms typically begin between the ages of 12 and 23. Copper plays a key role in the development of healthy nerves, bones, collagen and the skin pigment melanin. Normally, copper is absorbed from your food, and any excess is excreted through bile — a substance produced in your liver.
