Both selegiline and rasagiline can improve the symptoms of Parkinson's disease, although their effects are small compared with levodopa. They can be used alongside levodopa or dopamine agonists. MAO-B inhibitors are generally very well tolerated, but can occasionally cause side effects, including: nausea.

A febrile seizure is a convulsion in a child that may be caused by a spike in body temperature, often from an infection. Your child's having a febrile seizure can be alarming, and the few minutes it lasts can seem like an eternity. Febrile seizures represent a unique response of a child's brain to fever, usually the first day of a fever. Fortunately, they're usually harmless and typically don't indicate an ongoing problem. You can help by keeping your child safe during a febrile seizure and by comforting him or her afterward.

Cataplexy is a sudden, temporary loss of muscle tone that can result in collapse. It is often caused by intense emotions, including laughter

Acute compartment syndrome refers to ischemic tissue damage secondary to elevated pressures in the enclosed compartments of the lower legs or forearm. When the tissue pressure in an enclosed compartment exceeds the perfusion pressure, the resulting diminished tissue perfusion and compromised blood flow to the muscles and nerves inevitably lead to ischemic tissue necrosis. Majority of the cases involving the lower extremities are due to a traumatic event, most commonly tibial fractures. Other causes include a crush injury or other long bone fractures in a motor vehicle accident, a tight cast or dressing after trauma, and drug overdose.

Blood is a specialized fluid in your body that has four main components, each with a different function: plasma, red blood cells, white blood cells, and platelets.

Chagas disease is common in South America, Central America and Mexico, the primary home of the triatomine bug. Rare cases of Chagas disease have been found in the southern United States, as well. Also called American trypanosomiasis, Chagas disease can infect anyone, but is diagnosed most often in children.

A blood test to measure calcium, phosphorous and vitamin D levels can usually confirm a diagnosis of rickets, although your child may also have some X-rays or possibly a bone density scan (DEXA scan). This is a type of X-ray that measures the calcium content in bones.

Gallbladder cancer is cancer that begins in the gallbladder. Your gallbladder is a small, pear-shaped organ on the right side of your abdomen, just beneath your liver. The gallbladder stores bile, a digestive fluid produced by your liver. Gallbladder cancer is uncommon. When gallbladder cancer is discovered at its earliest stages, the chance for a cure is very good. But most gallbladder cancers are discovered at a late stage, when the prognosis is often very poor. Gallbladder cancer is difficult to diagnose because it often causes no specific signs or symptoms. Also, the relatively hidden nature of the gallbladder makes it easier for gallbladder cancer to grow without being detected.

CIN is a rare disorder and occurs when kidney problems are caused by the use of certain contrast dyes. In most cases contrast dyes used in tests, such as CT (computerized tomography) and angiograms, have no reported problems. About 2 percent of people receiving dyes can develop CIN. However, the risk for CIN can increase for people with diabetes, a history of heart and blood diseases, and chronic kidney disease (CKD). For example, the risk of CIN in people with advanced CKD (glomerular filtration rate (GFR) below 30 mL/min/1.73m2), increases to 30 to 40 percent. The risk of CIN in people with both CKD and diabetes is 20 to 50 percent.

Multiple myeloma is a cancer formed by malignant plasma cells. Normal plasma cells are found in the bone marrow and are an important part of the immune system. The immune system is made up of several types of cells that work together to fight infections and other diseases. Lymphocytes (lymph cells) are the main cell type of the immune system. The major types of lymphocytes are T cells and B cells.

Eye cancers can be primary (starts within the eye) and metastatic cancer (spread to the eye from another organ). The two most common cancers that spread to the eye from another organ are breast cancer and lung cancer. Other less common sites of origin include the prostate, kidney, thyroid, skin, colon and blood or bone marrow. Melanomas (choroidal, ciliary body and uveal) -Early stages has no symptoms (the person does not know there is a tumor until an ophthalmology examination). As the tumor grows, symptoms can be blurred vision, decreased vision, double vision, eventual vision loss and if they continue to grow the tumor can break past the retina causing retinal detachment.

Mitosis, a process of cell duplication, or reproduction, during which one cell gives rise to two genetically identical daughter cells. Strictly applied, the term mitosis is used to describe the duplication and distribution of chromosomes, the structures that carry the genetic information.

In nonsurgical treatment, progressive physical therapy and rehabilitation can restore the knee to a condition close to its pre-injury state and educate the patient on how to prevent instability.37, 38 This may be supplemented with the use of a hinged knee brace. However, many people who choose not to have surgery may experience secondary injury to the knee due to repetitive instability episodes. Surgical treatment is usually advised in dealing with combined injuries (ACL tears in combination with other injuries in the knee). However, deciding against surgery is reasonable for select patients. Nonsurgical management of isolated ACL tears is likely to be successful or may be indicated in patients:

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..
