Nerve Anatomy
Nerve Anatomy samer kareem 12,861 Views • 2 years ago

Nerves are the organs that make up the peripheral nervous system (PNS). They serve as information pipelines that allow the brain and spinal cord to communicate with other tissues and organs. Inside the nerves are the axon processes of sensory and motor neurons (nerve cells).

Amyloidosis
Amyloidosis samer kareem 21,330 Views • 2 years ago

Amyloidosis (am-uh-loi-DO-sis) is a rare disease that occurs when a substance called amyloid builds up in your organs. Amyloid is an abnormal protein that is usually produced in your bone marrow and can be deposited in any tissue or organ. Amyloidosis can affect different organs in different people, and there are different types of amyloid. Amyloidosis frequently affects the heart, kidneys, liver, spleen, nervous system and digestive tract. Severe amyloidosis can lead to life-threatening organ failure.

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..

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.

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.

MRI Uses in Multiple Sclerosis
MRI Uses in Multiple Sclerosis samer kareem 4,397 Views • 2 years ago

If you have multiple sclerosis (MS), you probably had several tests done before you received your diagnosis. There isn’t one test to diagnosis MS, so testing can vary. Doctors can use neurological exams, information about previous symptoms, blood tests, and spinal fluid tests. A magnetic resonance imaging (MRI) scan isn’t used to diagnose MS but rather to rule out other diseases. A diagnosis of MS requires more information than what a scan alone can give. By looking at more than one test or exam result, doctors can get a clearer picture of what’s going on in your body.

Trigger Finger
Trigger Finger samer kareem 18,524 Views • 2 years ago

Trigger finger, also known as stenosing tenosynovitis (stuh-NO-sing ten-o-sin-o-VIE-tis), is a condition in which one of your fingers gets stuck in a bent position. Your finger may straighten with a snap — like a trigger being pulled and released. Trigger finger occurs when inflammation narrows the space within the sheath that surrounds the tendon in the affected finger. If trigger finger is severe, your finger may become locked in a bent position. People whose work or hobbies require repetitive gripping actions are at higher risk of developing trigger finger. The condition is also more common in women and in anyone with diabetes. Treatment of trigger finger varies depending on the severity.

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.

Front Tooth Filling
Front Tooth Filling samer kareem 2,156 Views • 2 years ago

Tooth colored composite fillings are chemically bonded to teeth. For this reason, the placement of white fillings does not always require numbing the area being restored. Numbing (anesthetizing) the area is often required if tooth decay has progressed beneath the enamel layer and into the underlying dentin layer which surrounds the nerve of the tooth. Once decay is removed, the tooth is cleaned and a primer (weak acid) is applied to the area being restored. The primer opens pores in the enamel and dentin. A bonding agent is then flowed into the open pores and cured. Curing prepares the bonding agent to adhere to the tooth colored filling material. The filling material is then placed inside the tooth. After shaping the tooth colored filling material to resemble the natural anatomy of your tooth it is hardened by curing with a strong curing light. Once the white filling hardens, your bite will be checked to make sure your teeth fit together properly. If the tooth filling extends into the space between your teeth your dentist will also make sure you can floss between your teeth properly. Adjustments will be made if necessary followed by smoothing and polishing of your new filling..
